Diane Keaton and Jack Nicholson in Something's Gotta GiveSOMETHING'S GOTTA GIVE

In Something's Gotta Give, a sixtysomething womanizer, currently dating a twentysomething auctioneer (!), finds himself, for the first time ever, falling in love with a woman roughly his age, and - wouldn't ya know it? - it's his girlfriend's mother! Has there ever been so High a Concept? A forced, jokey premise like this is usually enough to make me hide under my theater seat; it's a situation so nakedly designed to provide good-natured chuckles and muffled sobs that a hardened cynic like me walks into the movie with all defenses immediately up.
