It's a fun game because it's an extremely fine-tuned platformer with great level design and great gameplay elements. Honestly, I have a hard time seeing how people get bored with it. It was significantly better than Mario 64.

From what I've seen, most people don't like this game for some silly reason or another. So, being "cool" or "going with the crowd" in this situation means not liking the game. Way to use those brains, smartass.
