My wife and I went to see it and I have to say that with the story aside it was pretty good. The action and explosion/gunfire sounds were amazing and the killing was nothing short of pure art. We went right after I picked her up from work, so there were only 12 people in the whole theater. It was the only time in my life I was cheering out loud when people were getting dusted.
The could have shown the knife a bit more though.
