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 in the third and fourth editions (they very, very briefly look at art from the fifth edition).

They also review art specific to popular campaign settings, such as Dragonlance or Dark Sun, but left out one of my personal favorites, Spelljammer. A continuation of this film into the third edition could have included art from Eberron, which was a different type of campaign setting, as well as the controversial Book of Vile Darkness. Maybe they could do this in a sequel. Anyone up for "Eye of the Beholder II: Behold Harder"?

A great film for fantasy art afficionados as well as a fun trip down memory lane for classic D&D players.
