Looks like this movie caught the overall feel of D&D pretty well. No attempt to be a Lord of the Rings-like epic, instead we have a party of misfits getting in trouble and figuring a way out. That's D&D. That vibe sold me more than the mimic or the owlbear.
Incidentally, while I hate the original D&D movie with a passion, I'd love to see the blue-lips guy make a cameo appearance. Like, chilling in a tavern somewhere.
