Very 'Saw' as other reviewers have said, plus a bit of Misery (an innocent person, or in this case two innocent people, kept captive by a crazed medic). A bit of Human Centipede First Sequence (a madman carrying out extreme surgical experiments). Very good on tension and suspense and overall pretty good and much better than I expected at the start. And I really wasn't expecting the ending! Along with the ambiguity as to what happens to the two victims at the end.
As I say pretty good and if you like the body horror category well worth seeing.
