Took a chance on the 3D import. Thought it would be a winner, what with Jeff Bridges involved. It's kind of a Lord of the Rings derivation.
I agree that the film is mediocre. Lots of plot holes. Pretty good CGI. Had to turn on the English subtitles, as this is one of those mixes where the actors tend to mumble their lines, and they're drowned out even further by background music and foley.
From what I understand, this is a "2.5D" conversion. There were some moments when it almost looked like something was going to leap off the screen, but never quite made it. Depth is pretty good though.
