This was not a good film. Poorly scripted and acted - the concept was not new, the effects poor and not a showcase for Arnold Vosloo who really is a half decent actor. I watched this under some protest and only remembered having seen it before towards the very end - it's that forgettable. The acting seemed to consist of a number of glares & looks devoid of any sincerity. I kept expecting this to actually get going and before long I was just hoping it would finish. As for the medical bits - well I wasn't expecting a true version of ER events but this was just comical - I am a Dr so know what I am taking about - and the operative bits were just plain silly.
Do not waste your valuable time - unless you have absolutely nothing else to do - go out, ring up a long lost friend, watch paint dry, sort out your sock draw, do some household task. AVOID at your peril.
