The reviews aren't mixed at all from what I've seen. It's plagued with really bad technical glitches across all the platforms. It looks like the One is the best platform to play it on, but you may want to wait for a patch.
Plus they implemented a review embargo of 12 hours after launch, which means they knew of the problems and wanted to get as many initial sales as possible before people knew about them. Add to that the fact that there are microtransactions in a full priced game, and chests that you can't open unless you install an app, and I wouldn't touch this one with a ten meter cattle prod.
I've got it for PS4, and I'm enjoying the game. I haven't encountered any glitches at all. Even teamed up with a buddy and his friend yesterday on online multiplayer and it worked perfectly fine.
