There were a lot of things I liked about this film. Some I didn’t.
I thought the actors were all good, especially Jason Momoa as Conan. Visually, everything looked as if was leaping right out of the books. They even got the feel of it right. Particularly the sand-men battle.
As for the stuff that didn’t work, there are a few really bad continuity issues that jerk you out of the movie for a bit.
I saw the 3D version which was good, but I’m not sure you’re really getting anything extra out of it you’d miss by viewing it otherwise.
