Super Mario Galaxy 2

So I beat SMG2 yesterday, by which I mean, I saw the credits. Not only is the ending cutscene less impressive than the epic mindscrew that was the first game's ending, but the boss fight was horribly anticlimactic. The level to get to Bowser was satisfyingly frustrating, but Bowser himself was easy. The Bowser Jr. boss fights were more varied and difficult... in fact, SMG2 generally had better boss fights except for the Bowser ones. Beating SMG1 left me with a sense of accomplishment. SMG2 was more a case of "that's it?"
