i saw this movie and and i do like horror movie . i do not know what to expect and but as soon the movie be on his way it be nice to watch it . the idea be pretty original and the acting be nice . especially jenna dewan a the exciting or evil tamara . the hard thing about horror movie and be to make a good end . but there the movie fail . for a change and a end scene in a hospital and where suddenly all employee be go . first you see doctor and nurse run around and but then they all go home . no cry for help while be chase by tamara and escape to the roof ( also a smart move . not ) and off course a kind of open end . no . the movie start great and the main part be nice to watch and but they really mess up the end use all clichés from bad horror movie . jeffrey reddick fail in my eye with this movie and after make some really quality movie like final destination 1 and 2. if you like a good horror full of cliché ending and tamara be a good movie to watch . for me and i like movie which surprise me .
