It also helps that Wei looks like a martial artist. Batman looks like a Gears of War character, and it looks real goofy when he does any kind of kick in Arkham. Batman's counter punches and backhands look awesome though, but there's one animation Batman does where he jumps up and does a split kick and it's the dumbest looking thing ever.
Yeah i think it was an inspired choice to get George St Pierre from UFC to do the mo caps for the moves.... the moves are so freaking bad ass
