Quite possibly the greatest film of all time.
OK the thing I hate about this trailer, is that almost none of the music you hear in it is actually in the film, which is good, because it sucks.
Scott Pilgrim vs. The World is an example of a film where the music is almost like another character in the film. The movie is awesome, but the music drives the film. It's what you remember the most days later after you watch it. Another example of this would be the Twilight movies. The films suck, but it's the wide shots of the Pacific Northwest and Canada, and the music that really drive the story for me.
