I was amazed when I found out that they were making a sequel to the horror that was the first Dungeons & Dragons movie. Despite the poor quality all around of the first one some people gave the source the benefit of the doubt and were willing to try it again. Thankfully this time the source material was taken more seriously and the project was put into better hands.
The result is a decent film with a comprehensible story, and decent production quality. The cast is by no means A-list, or even B-list; though they do well in their respective roles. The effects are alright, but if the movie had a better budget it would have been even better.
All things being equal this movie is superior to the first. DnD folks out there should like it and appreciate the detail taken to make sure the source material comes through correctly. It's a mixed bag on how much other people will like it. If you are willing to look past the lower grade special effects, and the cast of unknowns then you might enjoy it.
