Here, the zombie make-up consists of actors whose faces are painted green with latex paint. Since several are seen in the lake itself, a lot of the paint is, at all times, washing or falling off in pieces...
And the paint only extends to their faces. Their hands are usually still fleshtone.
As if that wasn't bad enough, the zombie attacks are even worse. The victims scream half-heartedly for a few seconds, then just look bored and look around absent-mindedly while they're being chewed on by the zombies.
At one point, a man's explanation of the lake and how it came to be filled with nazi zombies lasts about 1/3 of the movie.
This one is just painful to sit through on all levels.
