I love a good Michael Sera movie, and the latest one doesn't look like it will disappoint. Scott Pilgrim Vs. the World is the story of a boy, who after finding the girl of his dreams realises he has to defeat her 7 evil ex-boyfriends before he can win her heart. 
I particularly like Scott's girl crush Ramona Flowers, her hair changes colour throughout the movie. How cool is that?
