The original is more disturbing both visually and psychologically, despite being made in 1978. But this film, complete with high-tech horror effects and a psychotic performance from Ellen Burstyn, is a keeper. I watched both parts and found it a bit strange why they didn't just release it as a single film. I had the same technical confusion with Bag of Bones with Pierce Brosnan. You do have to seriously suspend some disbelief. While the original has its moments of cheese, and dated 70s gimmicks, it is far more believable than this one. Characters are relentlessly picked off in the most public of places and no one notices. An entire unit of gore and horror lurks in the bottom of a shady medical center and yet, despite a video clip of such horrors being on Youtube, no one issues a warrant to search the place. The victims of the conspiracy in the original were more elaborated upon (including an empathetic and very young Tom Selleck who meets his end in OR 8). Here, the victims are seen after surgery in their comatose states, so we have no connection to the human being who once was conscious and lived. The film underuses a very talented case, which includes James Woods, Geena Davis, and Lauren Ambrose. Their characters needed to be seriously elaborated on. Someone was having too much fun with the FX and not with the emotional meat which was desperately needed. It's more outrageously inventive than the original, but far less plausible or thought out. It's a fun, frightful romp that definitely is a grisly charmer and one to keep though.
