I managed to put in about 45 minutes last night  before bed.  I'm making sure that I watch all of the cut scenes, because I hear the story is decent.  So far I haven't been disappointed.  It is super metal, which, while not my thing entirely, is kind of fun.  The camera controls feel a little loose, and I find myself over rotating the camera often.  I also am having a hard time getting into the combat.  I feel like it is easy for me to start a combo that is going the wrong direction and become open to attack.  Perhaps that is related to the camera, but it is a little frustrating.  I also encountered on example of an invisible barrier preventing me from jumping off of a wall to the platform beside me.  It was clear that was where I needed to go, but it felt like I needed to be in a super-specific place to make the jump. 
 
I don't want to complain too much, however, because I am having a fun time with the game, and the story is really paying off.  I imagine it wont take me too long to get through the whole game, but you can never tell with a wife, baby and job.
