Uhm . . .
One word. USELESS if your a DM! Don't see this movie unless you're looking for a cinematic rollercoaster ride. The critics don't know what they are talking about, since as a Dungeons and Dragons movie this one is an Epic Fail (gad!).
It's pretty bad. Although they had a lot of good ideas, the movie isn't the best. I was deeply offended by it, so I couldn't enjoy it. You're better off seeing the original. Beverly Cross, Ray Harryhausen and co. made a better movie.
Gad, it was so bad. ):
