Yeah, I think them being involved in the MCU is potentially a good sign. People are talking about how you can't really do a single DnD movie (which, you can, but I get the point that a series allows more nuanced character arcs) and the MCU was phenomenal about doing small bits with characters and allowing other movies to take up the torch.
I don't think they will go the way of a comedy movie, but one that does use humor effectively would be nice. Hopefully though, they don't go the route of Beer Thor or Draxx from Vol. 2. Neither of those characters were really funny, they were just aggravating to me. I wouldn't mind getting some more snark like Tony or awkwardness like Peter though, I could see those working in a DnD movie.
