Unlike the 1980’s edition, I’ve seen a lot of these, including the entire bottom half of the list, and it’s no surprise they didn’t find a wide audience. Many of them were MEANT to have niche appeal. (Or, at least were inevitably doomed to niche appeal status.) Movies that are too dark, too cold and artificial, or too bohemian tend not to do well with American audiences, no matter their other strengths.
Strange Days (a movie I’ve seen a half-dozen times) had way too much Rodney King white guilt in it, and Falling Down featured way too many Left-wing political rants. Audiences, by and large, don’t like being scolded, unless the movie is very appealing and well done otherwise (see Wall•E).
The message for filmmakers is that you can offend the masses or you can appeal to the masses, but you can’t do both. Pick one and accept the consequences.
“Too intelligent and forward thinking for the masses”? Look, you can boost unfairly overlooked movies without being smug dicks about it, WatchMojo.
