Scot Pilgrim VS the World.

This is my favorite movie of the summer so far. It has everything. Guitars, groupies, Battle of the bands, video games, kung fu, romance, teen angst (it's just missing zombies). The editing style in the action scenes uses comic book panels and Anime style cuts which I love. They use a lot of captions, titles and onscreen labels which are way comical (think Fight Club, Zombieland,, Watchmen). I espeially loved the the one that explains the partitioning of his aprtment and what he shares and does not share with his gay room-mate ( Scott's gay room-mate, Mcauly Culkin's brother if I'm not mistaken, steals lots of scenes in the film).
The numerous video game references scattered throughout the film are also hilarious, from the totally recognizable Windows OS and Nintendo sound effects to the Sims style "Pee meter" hud displays when Scott goes to the can. His collection of stupid t-shirts is as impressive as my own. They make fun of a lot of stuff that bugs me personally, like pretentious Vegans (so hey, that must bug other people too!).

All of the battle of the bands scenes harkened back to my high school years. Being a guitar player, I was actually in a few of those, and never won! It's no wonder I liked this film. It's filmed in Toronto where the comic book on which it is based is from and it's great to see familiar locations in a cool film such as this. I'm constantly amazed at how the lead actor Michael Cera manages to play the same character in different films, ( Superbad,  Youth in Revolt , etc ). It's not for everyone though! Give it a shot!
