Joseph Anderson was basically right about this game. I think he was a little too harsh on it, but yeah, it's mostly uninspired, shallow, and full of reused content. Sure, Mario 64 reused content as well, but that was 20 years before this game's release. There's no excuse for it in this game. It took me a while to come back to this game and finish it. I didn't go for the extra levels, because I was very bored of it and only trudging on because I like to complete games when I can. For me, seeing the ending cutscene was enough.
