By which I mean is still funny, and has a minimal amount of jokes which aged poorly (not stuff that aged poorly from stuff they couldn't have known about, such as a joke about someone dying in a certain way, but then someone later died in a similar way, but aged poorly due to how problematic they are).
The Big Lebowski is still good and its problematic moments are realistic/character flaws iirc.
Wes Anderson movies age pretty well.
Fargo is still good.
Haven't watched any in a while but I bet Jackie Chan stuff holds up.
Smoke Signals is still good.
Also seconding Monty Python and Mel Brooks
