Ehh... I did watch the trailer now, and I must say it looks awesome!
I mean the poster is extremely pretentious, like a bad porno, and the concept is very stupid - turns out all you need to turn from a weakly 'kick-ass' into a bad-ass, is let a lion bite you, and drip some blood back into your wound...
But everything else is great, all the bloody kills and... oh, there's nothing besides that. Then all the bloody kills look awesome.
