The "Juno" controversy primarily revolves around its portrayal of teenage pregnancy and the attitudes towards abortion. Critics argue that the film romanticizes teen pregnancy and suggests it is a viable option without addressing the complexities and challenges involved. Some viewers felt it presented a misleadingly positive view of the situation, potentially glamorizing the consequences of teenage decisions. Additionally, discussions about the film's treatment of abortion and the characters' choices sparked debates about reproductive rights and societal perceptions of pregnancy.

In the movie "Juno," Mark (played by Jason Bateman) does not fall in love with Juno (played by Ellen Page). Instead, he initially seems to connect with her over shared interests and feels a sense of camaraderie. However, as the story progresses, it becomes clear that Mark is struggling with his own issues, including commitment and maturity, which ultimately leads to his decision to back out of the adoption. Juno's feelings towards Mark evolve from admiration to disappointment as she recognizes his immaturity.
