The wii-u has a lot of great games but I'd still call it a bad system. Okay, maybe not bad, but the interface, set up, eshop, and some of the features were really poorly implemented. Especially the parental lock. For some reason after being able to start bayonetta 2 just fine, parental lock turned itself on and wouldn't let me play any game with an m rating or higher. I couldn't turn it off either and mine was the only account on the system. If I made a new account, they all had parental lock on by default. I ended up having to do a system reset to get it to work which deleted all of my game saves. So yeah, fuck the wii-u.
The switch is much better in that regard though.
