Tbf, I kinda get it. Like, it's been a looooooooooooooong time since Tooie, so the game's got big shoes to fill. Tooie's already a bit divisive as is, though not to DK64's level, so I feel like a lot of the fanbase would be hoping for something closer to 1.
But there's the issue, it's been a long, long time. It's shoes are soo big to fill that people will play it and pick it apart because "It's not as good as the old games". We kinda forget that fanbases of these games tend to hold these games to such high degrees that if they don't satisfy all of our wants, needs, and give us a sloppy moppy on top of it all, people just tear into them.
That and Nuts n Bolts wasn't even THAT bad.
