Looks like campy, silly fun to me. Will probably watch at some point, but I am not expecting high level plot or storytelling. Trailers have a very spectacle-meets-quips tone, so I expect a few smirks and eye-rolls while watching (which is fine).
I don’t really get that bent out of shape about most fantasy and sci fi films, as I sorta live by the idea that if I start taking DnD too seriously, I’ve probably gotten to old for it.
The exception are movies based on beloved sci fi and fantasy books, which I am happy to rage about when they are done poorly. But generic DnD movies? I am much more forgiving, personally.
