Character Arc Critique Suggestions
Mr. Strickland Mr. Strickland starts off as a strict and authoritarian teacher, holding a personal grudge against Marty and his family. He strongly believes that Marty is a slacker and lacks dedication. However, as the movie progresses, Mr. Strickland begins to witness Marty's passion for music and his growth as a musician. This challenges his initial perception of Marty, leading him to reconsider his harsh attitude. Eventually, Mr. Strickland recognizes Marty's talent and hard work, and in a surprising turn of events, becomes a supportive mentor figure for Marty and his band. The character arc is quite effective in showcasing Mr. Strickland's transformation from a strict antagonist to a supportive mentor. However, it could benefit from more internal conflict and exploration of Mr. Strickland's personal reasons for holding a grudge against Marty and his family.
To improve the character arc, consider incorporating flashback scenes or dialogue that reveal Mr. Strickland's past experiences with Marty's family, which shaped his negative attitude. This will provide a deeper understanding of his initial bias and lend more weight to his eventual change of heart. Additionally, adding moments of vulnerability for Mr. Strickland, where he questions his own teaching methods and rigid beliefs, will add complexity to his character and make his transformation more believable.
Marty Marty's character arc revolves around his determination to achieve his goals and the growth he experiences through his time travel adventure. At the beginning of the movie, Marty is a talented musician facing obstacles in pursuing his passion. He is rebellious and determined to make it to his audition, showcasing his determination and resourcefulness. As the plot progresses, Marty becomes involved in time travel and finds himself stuck in the past. This experience challenges him to adapt to new situations and overcome obstacles. Marty's character arc reaches its peak when he takes on the responsibility of fixing his parents' relationship in order to ensure his own existence. This showcases his growth from a self-centered teenager to a selfless individual willing to make sacrifices for the greater good. By the end of the movie, Marty has learned the importance of family and the value of taking risks to pursue his dreams. The character arc for Marty is well-developed and effectively showcases his growth throughout the story. The portrayal of his determination and resourcefulness is consistent and allows the audience to root for him. However, one minor critique is that Marty's transition from a rebellious teenager to a selfless individual could be further explored and emphasized. The shift feels slightly rushed and could benefit from more scenes that delve into Marty's internal struggle and development. Additionally, while Marty's passion for music is established, his journey as a musician could be further explored to add depth to his character.
To enhance Marty's character arc, it would be beneficial to include a few additional scenes that focus on his internal struggle and growth. This could include moments where Marty reflects on his past behavior and realizes the importance of his relationships and the impact he can make on others. Furthermore, showcasing more of Marty's journey as a musician and the challenges he faces in pursuing his passion would provide a deeper understanding of his character. This can be achieved through scenes that highlight his dedication to practicing, his interactions with fellow musicians, or even his struggles with stage fright. By strengthening these aspects, Marty's character arc will become even more compelling and impactful.
Lorraine Lorraine starts off as a bored and overweight housewife, longing for excitement and adventure. However, after Marty time travels to 1955 and interacts with her, Lorraine begins to fall for him. She becomes curious and flirtatious, finding a new zeal for life and taking risks. As she spends more time with Marty, she realizes that her attraction to him is misguided, as she actually craves a strong male figure in her life. Witnessing George's bravery in standing up to Biff, Lorraine becomes impressed and adoring of him. By the end of the movie, Lorraine transforms from a victim of Biff's harassment to a confident and hopeful young woman who stands up for herself and is excited about her future with George. The character arc for Lorraine is solid and effectively showcases her transformation throughout the screenplay. However, some aspects of her development could be further explored and expanded upon to enhance her journey.
To improve Lorraine's character arc, consider providing more scenes that delve into her discontentment with suburban life and her longing for something more. This will make her initial attraction towards Marty more believable and relatable. Additionally, explore Lorraine's relationship with her parents and how their influence may shape her romantic ideals. This will add depth to her nostalgic and romantic view of love. Lastly, while her transformation from a victim to a confident young woman is evident, focus on showcasing her personal growth and how she overcomes her insecurities throughout the movie.

With Marty's encouragement and guidance, George finds the courage to face his fears and take action. His turning point comes when he stands up to Biff, knocking him out and protecting Lorraine. This act gives George newfound confidence and assertiveness. By the end of the movie, George has become a more self-assured individual, leaving behind his shy demeanor and embracing his own potential as a writer. The character arc for George is well-developed and shows a clear transformation from timid to confident. However, it would benefit from further exploration of George's internal struggles and fears. While his idolization of his father and desire to live up to expectations is mentioned, it could be more deeply explored to enhance the emotional depth of his character arc.
To improve George's character arc, consider including scenes or moments that delve deeper into his internal conflicts and fears.

He decides to take risks and change the future in order to protect Marty and ensure a better outcome. By the end of the movie, Dr. Brown learns to embrace his adventurous and curious nature, becoming even more eccentric and willing to take risks for the sake of exploration and discovery. The character arc of Dr. Brown is well-established and effectively portrays his transformation from a skeptical inventor to an adventurous risk-taker. However, it would benefit from further development and depth. Currently, the arc primarily revolves around Dr. Brown's reaction to Marty's claims and the realization of the possibilities of time travel. Adding more emotional depth to his character, such as exploring his personal motivations or fears, would allow for a more well-rounded and relatable arc.
To improve the character arc, consider delving deeper into Dr. Brown's backstory and personal motivations. What drives his passion for exploration and invention? Is there a specific event or experience that shaped his eccentric nature? Additionally, adding moments of vulnerability or internal conflict can create a more engaging arc. For example, Dr. Brown could struggle with the ethical implications of altering the future or face personal sacrifices for the greater good. By exploring these aspects, the character arc will become more compelling and emotionally resonant.

Throughout the movie, Biff evolves into a relentless antagonist, becoming fixated on tormenting Marty and making his life miserable. However, towards the end, Biff experiences a transformation. After a confrontation with Marty, he is humiliated and faces the consequences of his actions. This serves as a wake-up call for Biff, and he realizes the error of his ways. In the final act, Biff becomes surprisingly polite and eager to please, no longer the bully he used to be. He starts seeking approval from others and attempts to make amends for his past behavior, showing genuine remorse and regret. The character arc for Biff could be improved by providing more insight into his background and motivations. Understanding why he turned out to be a bully and what drives his relentless pursuit of Marty would add depth and complexity to his character. Additionally, Biff's transformation towards the end feels somewhat rushed and forced. It would be more effective if his change of heart was gradually built up throughout the movie, offering more believable character development.
To improve the character arc, consider incorporating flashbacks or dialogues that shed light on Biff's upbringing and the influences that molded him into a bully. This will allow the audience to empathize with his struggles and better understand his actions. Furthermore, show Biff's gradual realization of the consequences of his behavior by gradually integrating moments of reflection or small acts of kindness towards the end. Also, consider providing closure for Biff's redemption arc by having him reconcile with the characters he had previously bullied, further emphasizing his growth and transformation.
Doc Brown Throughout the screenplay, Doc Brown goes through a character arc where he starts as an eccentric scientist with a curiosity for time travel. He becomes torn between the potential dangers of altering the future and his insatiable curiosity. Initially, he is unwilling to accept information about the future, but as the story progresses, he realizes the importance of understanding the consequences of time travel. Eventually, he becomes more responsible and cautious, realizing that protecting the space-time continuum is crucial. This leads him to prioritize the safety of Marty and his family, showing a deep care and concern for their well-being. The character arc for Doc Brown is well-developed. However, it could benefit from more specific examples or scenes that showcase his internal struggle and growth. It would be helpful to see instances where Doc's curiosity clashes with his responsibility, highlighting the tension he experiences. Additionally, providing a clearer explanation of how his relationship with Marty influences his character arc would enhance the overall development.
Consider adding a scene where Doc Brown is faced with a difficult decision that tests his curiosity versus his responsibility. This could be a pivotal moment where he realizes the potential dangers and consequences of his actions.
