I've been involved in the discord community (e.g nookazon), twitter, reddit and other places and i can safely confirm i think this is the nicest, most positive one out of the bunch. We're all gonna be negative because we have such high hopes for the game and we all want it to be perfect, so i get it. I do agree with the others who are saying that the criticism will die down with the new update too. Just be patient and dont fuel too much of the negativity, for your own sanity and for the communitys sake.
I read a good quote earlier, something along the lines of "a loud minorty ruins it for the majority" and i think that applies pretty well here. There are definitely a minorty of people who are quite upset at a lot of the mechanics and techniques nintendo are using, and i know a lot of us disagree with their opinions. But these people are loud and passionate (theres no problem with that, just to clarify) and so the negativity always seems like so, so much because of this. Just keep that in mind!
