My take is probably different than most.
I was fairly happy with the overall quality and quantity of Nintendo games and there's even some really good third party games (if you're willing to acknowledge the fact that indies count as third party support).
Hell, I even love the Gamepad. I hate modern UI, that seem to take up half the screen and distract from the immersion, and the Gamepad fixes this. It's also fairly comfortable in my hands (though a bit too thick for my tastes).
But it all fell apart in the last year or two.
Nintendo has returned to 90's level of censorship, which doesn't bode well for the NX, and an aging fanbase that doesn't want to be treated like 12 year olds. They ruined miiverse with the constant updates and redesigns, it's now a shell of it's former self (it's long since been abandoned by the most popular posters and artists). And pretty much everything they've released since Splatoon has been a half-ass money grab: unfinished games, unpolished games, games that look like they belong on Apple's App Store, with very little is up the standards I'd expect of Nintendo.
Even Splatoon was released unfinished, and is still buggy as hell, and some of these bugs could be fixed with a single line of code. But Nintendo has made it clear, they no longer give a shit about the Wii-U, or it's hardcore fanbase.
So, for now at least, I'm pretty much done with Nintendo. My next console will be a Sony.
