I'm a 90s Adam Sandler movie fan at heart so any of those are my favorites, but special shout out to seemingly forgotten movie Dickie Roberts Former Child Star. I watched that movie way too many times as a kid.
Airplane! is such a quotable movie. So is Police Squad. They don't make them like they used to, those movies were a blast. It's not just the acting that nails things, but the writing holds up as well, which makes them stand the test of time, even with the changes in our culture.
I also still love Superbad, though that would probably never be able to be made in today's society without getting canceled. Pfft.
