Went and watched it just this afternoon so it's still fresh in my mind. I really enjoyed it with only one minor criticism. I saw the 2D version, and there were some action scenes in which it was obvious they were filmed exclusively for the benefit of the 3D audience. As such, some of the sequences were gratuitously longer than they needed to be for any plot development.
Like I said, only a minor nit-pick. Overall, the cinematography and acting were first rate. Hard to believe Christopher Lee is 90 and still maintains a strong screen presence. I also like James Nesbitt who's an incredibly under-rated actor and brings a lot of heart and a little humor to every role I've ever seen him in.
