You have to be so achingly accurate in the game, you'll rarely get the medals that are achievements for getting high scores. Plus, when you're off rhythm, your cohorts onscreen shoot you a dirty look. While this is at first hilarious, it begins to grate on you because the game is so difficult. Plus, content is locked until you pass a certain level of accuracy, which for some can be a game-stopping road block. If Nintendo had just provided modes like easy, hard, and superhard, Rhythm Heaven would have been a lot easier to like. As it stands, it's nearly a failure.
