Asking for no humor in a Dungeons and Dragons movie feels like sacrilege to me. Most D&D groups will either go goofy from the get-go or eventually evolve into it on some level, or you have the tryhards who want to make a serious and compelling narrative but ultimately results in either unintentional goofiness on their part (the 2000’s D&D movie was this, ironically for all the hate he gets it was clear Snails’ player was the only one who saw the stupid writing for it was and just went goofy so the other players pressured the DM to kill him off so they could get back to their “serious” campaign) or an edgelord “dark” story that will impress teenagers and people who thought Elden Leid and Akame ga Kill were good manga/anime.
And before anyone is all, “nah, bro, there’s legit good serious D&D novels!”, I’m not disputing that, but rather most DM’s ability to write their own actual solid dark campaign (and for all the players to stick to that tone).
This movie definitely represents what I think most people’s D&D campaigns are genuinely like. Also glad they’re not military or self-appointed “champions of justice”, but rather a rag tag bunch (who fucked up and have to fix their mistake probably out of pure self preservation) as I feel like that’s what a lot of parties end up being (or at least for a while). Though apparently that Rege-Jean guy is playing a Paladin so I could see him annoying the others occasionally with a bit of self righteousness.
