If this game was a person, it would be Meg. Unattractive and uninteresting.
To say the gameplay is mediocre would be an insult to mediocre things everywhere. The gameplay is bland and, worse yet, completely unbalanced. The game goes from being a cakewalk for long periods of time to frustrating due to piss poor controls and camera angles that are lacking at best. Unfortunately, there isn't a category for "Unbalanced" difficulty.
I'm a big fan of the show and I would be far more forgiving if the game was at least funny. But I hate this game.
