I might be a bit more lenient on this just because I'm a huge fan of D&D art as well as being an old school player myself. It should not simply be pegged as something only for fantasy nerds, and this film tries to show that. Including interviews with artists from D&D's days when TSR was still around, it gives an interesting explanations of the art and even delves into the creative process.
If I have a complaint, and it's a significant one, it would be the omissions. The film covers art primarily from the first and second editions of the game (it's currently in its fifth edition), which admittedly is the most iconic era of D&D. I would have been interested in seeing an analysis of how the art continued to evolve under Wizards of the Coast...
