the film have a good premise and a romanian prisoner and send on revenge mission and who can transform from human to beast and back again . yes and the survival film in a confined space have be do before . but what different be that youre never really sure when the beast be go to be monster and when it go to be human . the cast be pretty good and particularly marat glazer and aj hammond . jennifer wiggins run a bit hot and cold ( it feel like she get more direction in some scene and less in others ) and but it great to see a female action lead who can throw a punch and not look ridiculous . the beast design be well conceive . the shapeshifter have this strange ancient quality to him . the horn and the four finger hand and the nasty teeth it particularly effective when he get good and bloody up . the sound mix sound great on our system . the music be good and although it get a bit monotonous at time and at other time seem oddly absent . there quite a bit of gore and although certainly not nearly as much a dead men walk and another asylum film which be clearly shoot at the same location a shapeshifter . typical of film in this budget range and there be some part that work and some that do not . still and the good outweigh the bad and the whole thing add up to a fun low budget thriller .
