Very disappointing after all the hype.
That said; the game play wasn't fully flushed out. I think that the game play could have been smother over all and that the level design could have been executed in such a way that would allow you to move more fluidly through each battle. The controls where good but clumsy at times, like when you walking then all of a sudden your sliding, then rolling, then getting shot. At other times, you're in a fight and someone will come up to you with a shotgun and start shooting, and before you can turn around your dead!
It's these types of little problems that can ruin a game. All the game needed was a little extra attention in the end to make it "a great game that was every thing it could have been". Unfortunately they didn't, and the game really suffered because of the neglect.
