The Warcraft movie was entirely forgettable and it made me consider my desire to watch a Starcraft flick, which has a built in audience as well. While a hit like Stranger Things may have some D&D gags here and there, I don't see a great breakthrough when it comes to building audiences. But yeah, it makes a nerdy hobby into a pop thing I guess. And regardless of whether we're talking about high fantasy genre, or role-playing games mechanics; I think this might have better chance as a TV Show rather than as a movie.
