I just beat it tonight. The story was great. The dry humour was great. The action was great. And the overall tone was great.
One thing I didn't like however was the bullet time being locked for too long at times. Many deaths could have been avoided if it would just exit out of it quicker.
All in all it was a masterpiece. I don't say that lightly. I don't think I've ever called a game a masterpiece before. But this deserves it. Highly recommend.
