When I first rented this game, I thought I wasn't going to like it that much. But I started to play it and once I got the hang of it, it turned out to be a VERY addictive game.
The graphics are pretty good for the PSP in my point of view. The storyline doesn't really follow a lot of from the movie, but it's pretty good, too. It's hilarious when you attack someone, and the extras are amazing.
It's doesn't take long to beat, but it's taken me a while to unlock all of the extras. Very good game.
