I wrote a review of Scott Pilgrim vs. the World.  Spoiler: I found it pretty and pretty offensive.
 
I feel bad simply linking to another page in a blog, but the movie (or, at least, it's appeal) is so deeply entrenched in video game culture and history that I feel like sharing it with the GB as well as the Screened is a must. 
 
Edit: if you are about to comment without reading the whole thread, know that I hadn't read a single panel of the comics before watching the film.  Since then, I've started the books and I think they're much better.
