aka Les Memes Cannibales
How bad is it? It's of incredibly poor taste.
Should you see it? If you're not easily offended, it's got some laughs.
Released by Troma, this is a Belgian film that's much better than most of their in-house productions. First, though, they're not grannies and they're not rabid; the original title is closer to the truth. The film starts very slowly and has a few laughs because every character is truly awful and treats each other badly. Then a demonic present changes the two old ladies and some spectacular (for the budget) gore effects ensue, as the old women dispatch each of their guests. It's crude and very ugly, but it is watchable.
