As bodies start piling up, a couple realize their small town is under attack by a strange parasitic organism that feeds on it's host and then savagely kills them, forcing them to find a way of stopping the menace.
This was a pretty decent overall effort that doesn't really have all that many flaws about it. Among the better aspects here is the rather nice nature of the body-swapping parasite that attacks here which manages to keep this one with an air of mystery about it as to who is the next host of the dangerous creature, and the mythology surrounding that is rather nicely accomplished here. That also leaves the attacks to be developed quite well with the film resorting to simply miscommunication and obscure behavior at the beginning to really letting loose and showing off the deformed bodies as the parasite's activities get more pronounced and aggressive resulting in stellar action scenes as well. There's the fine jail-house ambush that results in the police chase through the streets upon the escape, a wonderful stalking scene in the bowels of a hockey arena following a great confrontation in the locker room and the finale in the motel room is really enjoyable with the change from the supposed seduction offering plenty of creature fun with the escaped creature switching around bodies trying to escape while the few known containment tactics are put to great use. Still, there's a few small flaws here starting with the silly need for the film to go so far into their back-story history that it tends to really grind the film to a halt since the initial outbreak and possession by the creature is done in the film's opening scene which is setting this up for a thrilling pace only for the love-struck romance to get featured and pull that down. As well, the decision for each of them to be in romances that are thrown away simply to bring them back together doesn't make much sense beyond adding to the body count and there's so much missed opportunities to be had from the fact that they stumble upon the creatures solely because their possessed activities are mistaken for cheating on them and then get swept away from there. As well, there's the film's incredibly lame and really unbelievable CGI present which doesn't make much sense at all and really does tend to expose the cheapness and limitations of the story by not really featuring all that many impressive attributes to the story whenever they're featured for its' not just for the creature and the gory aftermath of it's attacks but also for some really explosive action scenes which really highlights those issues. Otherwise, this one wasn't all that bad.
