Jason Marc Schoener’s review published on Letterboxd :
This film might not garner any Oscar nods or year end best of lists, but for pure ass kicking enjoyment, it's a definite pleaser. The beautiful Gina Carano excels in the physical aspects of the movie, even though some acting classes wouldn't help. But you don't watch this movie for the acting or the character arcs, you watch it for the action. In that sense it delivers. Soderbergh shoots and edits this movie with cat-like agility and makes the wise move to drop the score during the fight scenes so we can cringe at ever bone crunching punch. Take it for what it is, a B-movie made a gifted filmmaker.
