I've watched the Italian trailer, I can already say that I'll be watching it in English, because they little I heard about the dubbing and the translation was horrible. This is something that might affect this movie indeed, I mean poor distribution investments and choices (and I suspect that that has been, partly, the same issue some of the older D&D movies had).
edit: forgot to answer to this
I concur, but that's expected.. I mean, seeing the past flops of D&D movies, they are most probably pointing towards attracting as much people as possible, to being with. Dragons always work nice, humor does the same, some sexy stuff can do wonders (The Witcher anyone? ). I would expect all those elements to be in it, and I could be fine with them as long as there's a solid story in the background, I mean the kind of straight story which makes up for good D&D plots (anyone who played D&D long enough knows that the best games are those with "simple" plots, regular characters and so on and on). Going for the glorious plot, once you have so many things to unravel already, is not a great choice IMO.
This is what they did with "The Legend of Vox Machina" IMO. Stereotyped characters, plots which are rather simple. I guess any show that would actually be able to convey what a real D&D game is, instead of just going epic, would be a good show.
