9. Scott Pilgrim Vs. The World: Scott Gets With Knives
Some comic book movies work well as page-for-page adaptations which remain true to their source material, but Scott Pilgrim vs. The World did that to a fault.
In Bryan Lee O'Malley's graphic novels, the eponymous protagonist ends up with Ramona Flowers, even though their relationship is about as unhealthy as they come, largely based on insecurities. And the whole 'seven evil exs' thing? Come on!
Edgar Wright's film adaptation had the chance to right this by having Scott ultimately coupled with Knives Chau, who doesn't feel like his perfect match either, but she would have been a less toxic candidate than Ramona.
Wright almost had the balls to do this, filming an alternate ending where Scott and Romona go their separate ways, and the former becomes an item with Knives, but it wound up among the home media bonus features.
