How bad is it? It's dreadful.
Should you see it? No.
A woman sets up a team of housewives to be hired assassins of men who cheat on their spouses. It's talky, poorly shot and the actual sex and violence is boring. The scene of the guy with a nun fetish looks like it might go somewhere, but it's a brief shot of nudity and then an uninteresting killing, just like the rest of the film. The director seems to think he's making some social commentary, which just makes it drearier.
