The female thing has always had to do with the game (or in this case, movie) being appealing to its target audience, namely 12-25ish males who like to look at pretty-looking females, rather than some ape-like abomination of a female. I know the demographics have changed quite radically over the past few years, but I'm quite sure that was the initial line of thought.
Still, I don't really take that as the biggest issue in any of the footage shown. I'm mostly just concerned with the quality of the CGI, though I'm sure the low res quality of the clip has something to do with that too. Something with the textures, lighting and just the general looks that make me wonder if it's actually the same, or even higher, quality as the original cinematics from Blizzards were. Story-wise, my expectations are incredibly low as it is, so I doubt that'll be a point of criticism from my end anyway. So with that out of the equation, I'm actually carefully optimistic about this. If only for the sheer amount of popcorn potential.
