I just saw the Dungeons and Dragons Honor among Thieves movie and to be honest, I loved it. It is campy in the way the recent Jumanji movies are campy, it pulled from authentic D&D lore and was set in the Sword Coast, referencing several actual locations and NPCs in that world. What I really liked about it was that it felt like the story could have been lifted from an actual gaming table. Some of the dialog actually felt like players trying to figure things out before they role the dice, there was commentary on how arbitrary some of the D&D rules can be, some of the connections between characters and NPCs were only strong enough to get the story from one point to the next (which is typical of the game: the storyline is never airtight, only good enough to get to the next point of action), and I found the whole thing to be hilarious.
That is my vote.
