A comment on IMDB says it is "Rocky Horror Show on Stereoids"; watching the trailer, it seems an adequate comment. The Movie site says it has catfights with gorgeous girls (and they are really stunning!) but I guess I will have to be happy with a few seconds of women fighting that will be hard to find in hours of explosions and gore.
Anyway, let us wait until January for the official release. Thanks to the reader who made the hint.
