aka Lady Killers, aka National Lampoon's Lady Killers
How bad is it? The worst of the National Lampoon franchise.
Should you see it? God no.
Two hapless thieves get beaten up by two older women they try to rob, then end up marrying them for their money. The women don't actually have money and plan to kill their new husbands for insurance. Meanwhile, the audience contemplates suicide. Louise Lasser and Renee Taylor are wasted, the one joke premise of trying to have sex with someone you find repulsive doesn't work and there is nothing else to recommend it.
