Some marketing dingbat decided to release this to certain markets as "Dragon Mountain", which brought some negative reviews. The true name "Dwarves of Demrel" carries far more integrity to the movie, since that's what this is about: three dwarves trapped in collapsed mines.
This is a slow-burner of a movie that at its best presents some decent drama and character presentation... and at its worst makes no sense at all.
The creature offered no explanation other than "scary mystery element" that would have been better left out of the movie. The human character's presence is undeveloped and unexplained. The first 3/4 of the movie involves development of what really gets down to resolution in the final quarter. It is the final quarter that pulls this movie out of the trash bin.
I give this a "mediocre" 5 for effort, since it had a pretty decent final 15 minutes. But there was just too much of this movie that consisted of barely-audible dialog and gaping plot holes. With a little more effort this could have been a sleeper classic, but they just didn't quite get there. Those who rated this 8 stars and above have, I think, significantly lowered their bar on what makes a movie great. This is an interesting watch with real potential, but they missed that bullseye by a couple of rings.
