Pick the worst mother-in-law

Endora from “Bewitched”: Always turning you into a chimp or casting various annoying spells on you.

Mary Hatch’s mother from “It’s a Wonderful Life”: It was pretty clear she wanted Mary to snuggle up to that rich Sam Wainwright. What are the chances she would have ever let that go?

Norman Bates’ mother from “Psycho”: She was quiet. But maybe too quiet.
