the film doesn't explore it as well as the comics did, but the story is about scott being a shitty, under-developed 23 year old. he is confronted with his past and forced to reckon with how terribly he has treated the women in his life. scott is supposed to help ramona defeat her evil ex-boyfriends but is faced with that prospect that he could become one if he doesn't become a better person. i'd really recommend reading it as the film gives the wrong impression of the story

Scott Pilgrim is an immature, self-centered little dork with the biggest case of literal main character syndrome. He's a dick to everyone, and that includes being sexist. That's the character, not the movie.

I understand your confusion though, because the entire narrative is built around Scott's delusions. All of his insecurities and foolish notions are played out as if they are reality, because for the intent of this story as an internal reflection of Scott's psyche, they are.

The comic is about the journey of discovery in which Scott and the reader slowly find out that Scott is a shitty guy to everyone. The movie tried to condense that into a fun, short action movie, losing the message in the way.

Yeah, I particularly also felt that Michael Cera was a disastrous miscast, especially since like one of the first things you hear in the book is that Scott Pilgrim is known to be the toughest fighter in his entire province. They really should have went with Jesse eisenberg at the very minimum.
