I myself am a Fan of PM64 and TTYD as well, and I just don't think this game is that bad.
The Dialogue in this game is epic, and so far all the bosses have been great and fun to do if you don't instantly use it's weakness (Keeps the better music on during the some Bosses <_<).
I'm enjoying the Multiple Exits as well.
From what I've seen, people are mad about there being no exp. We don't have Badges though, so you don't need BP or FP. Which would mean leveling would just give HP. They took an alternative from another series I love, and added what are basically hidden "Heart Containers." I thought this was awesome. Promotes more exploring.
IMO, Stickers are good. Makes it so you have to think about what move to save for certain situations. Plus they aren't that hard to get.
The Soundtrack is pretty nice and the levels are interesting enough for me. I just don't see whats so bad.
