There is no shortage of violence in video games. Violence in games that doesn't translate to the movie is weak. If you can butcher someone in a video game, I expect the movie to have the same level of gratuitous violence.
Long ago there was a movie called Mortal Kombat. That movie sucked, and more a kin to The Last Dragon.
This movie which is apparently a pitch to studios for a budget looks like it could be incredible. Yes that is Michael Jai White, and Jerri Ryan.
