In this interesting sequel, the flesh eating virus that panicked a handful of college friends in the woods manages to attack a whole high school. Gone is the slow burn fear of contamination, and wondering who had it and how the friends would turn on or help each other. Instead we have the local hick water company infecting them on a mass level by supplying contaminated bottled water. The inclusion of the dopey deputy from the last film is fun, and the concept is exciting, but its highly patchy. Rider Strong makes a quirky lead with a believable painful crush on friend Cassie, but his best friend is an pain whose world-weary schtick soon tires, and its hard to care about any of the vain, bitter self-centred teens in this movie. Also the virus progression itself is a problem. In the first movie it took about a day and a half to 2 days to manifest scratches and sores. Here, they're spewing their guts out (literally) within minutes of drinking the contaminated water. For gorehounds there's some brave and strong horror gore, but it's hard to care about the people it's happening to. There are also ludicrous holes in the plot that make it plain silly (SPOILER:) with the military surrounding the school and machingunning everyone they find, but then conveniently leaving one of the largest exits both unchained and unwatched. There are clever aspects - the little cartoon describing how the virus got transported to the city is daft but clever fun, but nobody is going to touch a hooker who looks like that (you'll see what I mean), and the desperation with which it's left open to a slew of multiple sequel angles is almost too eager to keep it beating.
