Watched this last night.
Pretty good fight scenes with no CGI, which I liked. The lead actress used a lot of MMA-style submission stuff. Armbars, guillotines, even a triangle choke.
Unfortunately everything else sucked, so the movie was not very good. It had a weird mish-mash of a cast also. Antonio Banderas, Ewan McGregor, Bill Paxton, Channing Tatum, Michael Fassbender...WTF? Gina Carano was hot and did well in the action sequences, but she stunk as an actor.
