"It's disappointing due to what this game could have been."

Games based on comics/manga/anime/movies/etc are pretty much never any good, really. The only good ones I've ever played are Marvel Super Hero Squad and the Bleach games on the DS. They capture most of the spirit of the shows/comics and are actually fun to play. They both also have quite the amount of collectibles, which is lovely if you're a loot whore like me.
