One thing to remember is that most blockbusters make the majority of their money in non english speaking countries, particularly china.
Dialogue and culture is hard to sell to different groups, so you tend to get a lot of the "robots go boom" movies as it's universal and easily understood.
If the D&D movie is going to try and compete in that space, expect it to be much more about exciting combats and special effects, and of a more basic dialogue and plot development.
I'm expecting it to be more Guardians of the Galaxy in approach then say Transformers.
