Trying to say "Sorry, Thor Wii" 3x fast is more fun than playing it.
I can't tell you any of Thor Wii's characters, plot, goal, bad guy, or setting. None of it made sense (and I played it all the way through)! While it certainly isn't for those unfamiliar with the movie or comic books, it's at least passable as a beat-em-up/brawler.
