Raze

On the down side a somewhat well worn storyline of people suddenly waking up in some undisclosed secure location and have to fight or kill follow abductees to find freedom. Has been done in many manifestations before. Nothing new here; same cameras with our hidden captor at first known only through their voice. Typical cage fighting - martial arts or whatever one can come up with for fighting. Back story, also done before, of wealthy audience being entertained throughout as inmates fight-for-life. Overacting, bad person roles especially; thus, not too believable. Ending scenes came across as even less believable and therefore viewer engaging.

On the up side, follow up with the slightly similar "The Seasoning House".
