Yeah, the 90s were a good time for movies that could not have been mainstream in any other decade. I’d place Judge Dredd, Demolition Man and Total Recall in the same “corny, but excellent” league as the 5th Element.
Then you had unofficial double features of sorts: Smoke/ Blue In The Face, Casino/ Goodfellas.
12 Monkeys needs to be mentioned as well, it’s probably the most palatable movie on my list.
In the “disconcerting, but unforgettable” league, I’d place As Good As It Gets, The Crossing Guard and, of course, the grisly “8 mm.”

Oh, yeah. It unofficially spawned “Friends,” too. Also, if you watch the music videos of the OST songs, you’ll find many (all?) of them have a “Singles” movie poster hanging somewhere. What an amazing level of coordination.

Yeah, it feels quite petulant and deconstructive at times.
But a lot of what you wrote is just a feature of any small online community. Then you end up with these bitter types who, if you rubbed them slightly the wrong way, get up at 6 a.m., downvote everything you ever wrote and report as many of your contributions as they can get away with.
I mean, downvotes and upvotes could be capped at -1 and +5, respectively, like on /. which has been going strong for more than 20 years with this concept, or there could be enforcement of some sort of netiquette, but that would put additional strain on the mods.
