Cabin Fever

A group of horrible teens arrive at a small town the residents of which are even more horrible, and there's also superaids in the water supply. The superaids is incidental, and I'd argue it's even a red herring of a threat. The real threat is obviously how a supernaturally horrible human being everybody is.

In the universe of Cabin Fever, no problem ever gets solved since it is always someone else's problem, until it becomes everyone's problem at which point no one has the power to solve it. It is a downward spiral, a representation of entropy that we are all very familiar with in real life and we know from our real life experience that any and every problem the characters in this film face will result in a major catastrophe due to people's unwillingness to deal with it at any of its stages.

Although there are a few intolerably disgusting frames that might get to you, it's more comedy than horror. Because you can't really feel too bad for anyone dying in agony when they kind of all deserve it. I'd argue we shouldn't feel bad, neither for the characters nor for their reflections in real life. Just keep selling the superaids lemonade like the good "BUSINESSMEN" we all are and get over it.
