I'll mention something different for my own contribution than my usual:
I've always hated Seinfeld, including when his show was brand new. "It's a show about nothing!" was a thought terminating cliche in the 90s that was used to pitch the show at me again and again by its fans, and also to dismiss any and all problems I had with the show and its ultra-privileged smarmy main character. If I got anything valuable out of that show and for that matter his stand up routine, it was a lifelong allergy to New Yorker comedy that front loads a whole lot of "I am a New Yorker which means I am smarter and tougher and wiser and more cultured and more sophisticated yet more grounded than you" self-aggrandizement into the set. :nyet:

Holy Grail derailed hundreds if not thousands of hours of D&D sessions throughout the 90s. It was memes before memes were a known internet thing.
I didn't hate either of them but the cliches were grating over time for sure.
Yeah, the quoting of Holy Grail was far worse than the actual movie
