I've never experienced a new console release where so many people went out of their way to create negative threads about non-issues. I wonder why?
It's fascinating to watch.
As someone that doesn't want it to fail but will just roll my eyes when it does, it's because Nintendo (and it's defenders) are good at generating anger toward them.
They made a system again that's a lot like the Wii U which already failed in many peoples eyes. Why don't they learn? The Switch is technically speaking already old, over priced in many people's eyes (why no pack in game?), and has a single game that people care about until maybe Arms or Splatoon 2 launch. There are zero additional media options on it like Netflix or even Youtube. They're charging for online...there's just a lot of bad shit surrounding it.
On top of it all they don't talk. We don't know enough about the system, about any of the issues brought up so far...they just don't talk and it's easy to get mad about that.
I personally want it to succeed, but I don't think it will the way they're going about it currently. I have no doubt they can completely turn it around but I'll praise that when it happens. It hasn't yet.
So there I think is your honest answer.
Edit: Oh and the defenders. Just read the replies on this very page. That generates anger and more negativity.
