As a stand alone movie, I'd say this was a well made flick. However, knowing it is a prequel, it is difficult not to compare the movie with it's predecessors. Decent acting ... nice special effects ... great story and camerawork. I would recommend seeing it but I wouldn't waste the money to see it in the theatre or in 3D. There are only a couple of places where the 3D really enhances the film.
Pros well paced, great story
Cons not enough 3d, nothing compared to it's predecessors
