I'm in the controls made the game unenjoyable camp. I'll even say, it's not necessarily the controls, as in motion controls. If you have Starfox 64 3D, it ends up being much like the gyro controls. The difference, is around once per level you are forced into using the second screen, particularly as a mechanic during a boss fight or final action sequence. The second screen also makes firing significantly more accurate, but at the cost of running into nearly everything you could possibly crash into, as you have to look down to aim, and look up to fly/navigate.
This was the first game I bought and played on my Wii U. Nearly everything else about the game is just more of the Starfox you already love, except your not allowed to enjoy it... I personally don't mind motion/gyro controls. Stuff like Okami and RE4 play best with motion controls in my option, but SF Zero just was a failure of implementation in my experience.
