Good Lord, practically everything is on someone or another's dislike list. Some hardly seem in keeping with LK's original question of "Things Other People Like." Who likes bitchy women or ill-behaved children, to cite a couple of examples.
Much that I don't like has already been covered. and much that I like (e.g., guns, blondes, beer and the beach) is one somebody's dislike list.
I'll toss out a few more of my pet hates:
Any movies based on comic-strip superheroes.
Any movies featuring young people imperilled by homicidal maniacs.
PETA and animal fanatics in general
The anti-fragrance movement
