The gold thing is that, you didn't even need to knew anything from the forgotten realms, or from dnd in deep to know understand and enjoy the movie. They could use names like Neverwinter, that, will mean nothing for you, but you understand is a important place, and you being one Lord is a big deal, if you do know then though, that is even more exicting to catch the the references
I think the warcraft movie could also have worked, if they actually tried to adapt the story of the first war, in a 3 hour movie, not ina 1hour movie.With the D&D movie its just a band of people who aren't making history or lore of events. Had the Warcraft movie been about a group of 5 people going through an epic quest chain, complete with game references, comedy and cameos of famous NPCs, people would have LOVED. IT. Instead they choose a story all the fans knew about and read, fantastically told it incorrectly or changed things around, and somehow made it a joyless, unsatisfying movie. I haven't watched it since it first came out in theaters, I just remember it being not colorful, dark, no memorable action scenes and melancholy in a boring way.
That would work much better in a tv-show, that blizzard is sleeping on it, a faithful story of that time would make as much buzz as house of the dragon imo, if they make grit and dark.
