I really want to see it, because basically the universe of Scott Pilgrim, is a comic book/video game universe, which is why the previews have the large words of "kapow" and random announcers screaming, "K-O!"
As far as the comic book goes, it's mixture of a manga style with western influences, it's good and it is definitely funny. The universe in the comic is still the "videogame/comic book universe" and is really intriguing.
I'm desperately hoping that it will be good, so, if you feel like having a laugh with seeing really over the top fights, go for it. If you still feel a little hesitant, there's this one reviewer on the web who I tend to agree with on movies, he's located here: [link]
He has a review every Friday of the newest biggest movie to come out, so, yeah best of luck ^^
