10 Awesome Movies Where The Bad Guy Wins

8. If You Can't Beat Them... - Rosemary's Baby

Roman Polanski's terrifying classic remains one of the greatest horror films of all time for good reason. Rosemary's Baby revolves around a young couple, Rosemary and Roman (Mia Farrow and John Cassavetes) who move into a new apartment block, and before long Rosemary discovers that she is pregnant. However, strange goings-on begin to make Rosemary suspicious of her neighbours; rumours that the block used to be inhabited bySatanistsand witches does little to help.

In the end, it turns out that there is a coven operating in the tenement, and Roman is in on it; the son is not his, but rather the Devil's, and Rosemary is left with a choice; abandon her son, or enter into the coven and care for him. Going by the haunting final imagery, it appears that Rosemary has decided that if she can't beat them, she might as well join them, a terrifying note that lingers in the viewer's mind long after the credits have rolled.
