The Swimming Dead
In the predictably lifeless Dead in the Water (2006), two teen sisters take their boyfriends up to their parents’ cabin by the lake for some bra-unclasping action and zombie encounters. One of those activities is a real mood killer.
As night falls, the living dead come out of the lake and track mud all over the place. Everything is filmed so dark you can’t tell whether the zombies are wearing swim suits or not. The kills are weak, as is the storyline (something about a zombies coming back from the dead).
One of the girls finds a severed arm in the water. The zombies come back to get it. I think. Scratching herself with the dead hand, the girl becomes infected and… You know the rest.
If all of this sounds like a rehash of the The Evil Dead (1981), you get a cookie.
