Bayonetta
The tutorial was more interesting than I expected - performing impressive and fun moves is actually pretty easy. And between the punching and kicking and guns and bullet-time and shit, there is certainly a lot of (easily accessible) variety in what you can do.
But then I got to the part of the demo that actually represents the game. Monsters everywhere! I can't see shit. Difficult to dodge when I can't see what's attacking me. And apparently there was a giant monster in the background, too!
For me, it turned into a nonsensical button masher, followed by my death. A fan of the Devil May Cry series may see some sort of strategy and technique in this; I wouldn't know. All I saw was visual noise and bare thighs.
