The movie was definitely shot for 3D. A lot of the movie takes place in the mines and at night, so there are some dark scenes. Overall a lot of fun, though, with one scene containing a lot of nudity, and some scenes having the gimmicky pop out effect that some people here hate. I actually liked some of the pop out stuff with the pick ax, and perhaps the best one was the shot of a motor that seemed to extend out of the frame during a "normal" scene. With not much else available to us on 3D Blu-ray, this was a welcome addition. Sure it's overpriced, but even Best Buy knows that all of the people that bought new 3D TVs are starving for 3D content.
