Edgar Wright who is responsible for films such as Shaun of the Dead and Hot Fuzz made this "video game" movie starring Michael Cera, an actor I'm hesitant to give a chance. Thanks to movies like Youth in Revolt.
The film has a very very unique style. The humor is witty and requires you to pay attention to elements in the background. Cera was actually enjoyable to watch, which I doubt I've said before. The premise of the film is that he falls for the new girl in town, trouble is, she has evil ex-boyfriends that he must defeat to win her. The fights with the ex's usually mean that they are given "life energy bars" like in Street Fighter or Mortal Combat, and upon being destroyed "points" are earned as they turn into coins like Mario Brothers.
I won't deny that this is a tween centered movie and that some demographics wouldn't get or like this film, but I really did and would suggest it to that age range.
