The plot: Four friends go on a hunting trip in Texas, only to run up against Chupacabra zombies.
Well, there isn't a lot to say about this film. It's pretty stupid, but I was still amused by some of the scenes. Much of the humor depends on your being an immature, easily amused film nerd. If that's you, then you might like it, too. Just be aware that it's not really action-packed or fast-moving. Despite the bizarre premise, it's not really the most original horror-comedy ever made. It clumsily adopts and mocks every cliché the writers could think of, though not on a terribly intellectual level. It's quite inhibited compared to Troma's sheer insanity and gleeful offensiveness, but there's definitely a bit of inspiration from that infamous studio.
Normally, my tolerance level for these films is quite low, but this one had just enough stupidly amusing scenes that I stuck it out. Also, I liked the end credits song. If you like this sort of nonsense, then I suggest you check out DeadHeads, another recent zombie comedy that was similar in some ways.
