As someone with a deep appreciation for D&D artwork and a long history playing the game, I’m inclined to be understanding of this documentary. It shouldn't be dismissed as solely appealing to fantasy enthusiasts; the filmmakers attempt to demonstrate its broader appeal. Featuring conversations with artists from when TSR was still involved, it offers insightful looks into the art itself and how it was created. However, a notable shortcoming is what’s left out. The film largely focuses on artwork from the first and second editions—the most recognizable period for D&D—though the game is now in its fifth iteration. I would have appreciated an examination of how the visual style changed during the third and fourth editions, even if it was brief; they only briefly acknowledge the fifth edition’s art. While the documentary does showcase artwork related to well-known campaign settings like Dragonlance or Dark Sun, a beloved setting for me, Spelljammer, was excluded. A follow-up film exploring the third edition could have included Eberron, which presented a distinctive kind of campaign environment, as well as the Book of Vile Darkness, which generated considerable discussion. Perhaps that could be something they address in a future installment—"Eye of the Beholder II: Behold Harder," anyone? It’s an excellent film for those who enjoy fantasy art and provides a nostalgic experience for veteran D&D players.
