I am currently playing the game and I am finding it really good.
I do like some violence in my games, however I can't help but feel that some of the environment kills are not brutal enough (throwing them into a bin? lol. The press that crushes the head is pretty good though). Also there is a heavy lack of blood (in terms of killing your enemies).
That said, I do like it. The crime scene stuff is really cool, and they did a great job of body awareness (the camera movements when climbing, you can see your arms and legs). I am not very far into the game (up to the museum) but so far it is quite decent. The combat is also unique (in a very good way), and the enemies have decent AI.
The graphics are also fairly nice. The cut scenes, however, do leave something to be desired.
All in all, good game. 7.5-8/10 for me (note that I have not completed the game).
