I like the physics, and the improved combat, voice acting was nice.
Although I like that it isn't frustrating to find some things anymore, I feel that the solution to that problem was too extreme.
I enjoy the "perks" that you get at the specific levels, only I feel that they be available through other means, instead of just unlocking.
It nice that you don't miss when physics dictates that you should hit, but I wish they would have implemented character skill in combat areas not associated with missing. Improved A.I was great, made the world feel more alive.
There's a lot more I enjoy, but most of it, could be even better.
EDIT: Traps! Of course, traps.
