I, too, am hopeful for some continuations along the same vein - but as always a successful thing in media tends to attract the attention of studios and other unhelpful folks that meddle too much in sequels.
They should have called it something else. There's clearly a market for fantasy, as has been seen with the popularity of Netflix's Witcher series (which treads very similar ground), but the Dungeons and Dragons brand has been thoroughly devalued over the years, and doesn't have the same kind of mass-market appeal.
I think it might be because of the OGL scandal (when WotC tried to use a loophole in the license text to turn an open license into a closed one).
At least that was my personal reason why I decided not to watch that movie, and not to buy anything from WotC anymore.
