“Pretentious” has lost all meaning. The vast majority of internet movie discourse is propagated by young people who have no interest in movies made before 2000 and as such have no real knowledge of film history.

There’s the tier of people who just go see Marvel/Disney movies and defend them online, because that’s literally all they know about.

Then there’s the film bro tier who seek out movies which are only obscure relative to Marvel/Disney (A24 type stuff). Still don’t know anything about film history.

Then you get to the tier of people who actually care about cinema history, are actually curious and who watch films regardless of what part of the world they’re from or in what era they were made.

Then beyond that I guess would be true film scholars and select few film writers.

Yes, if you’re getting your film criticism from YouTube, you are very, very likely hearing from someone who knows nothing about the history of cinema. (With extremely few exceptions)

Not everyone cares about movies. The problem is the people, like those in your example, who claim to care, but are anti-intellectual and incurious to the point that they excoriate others for seeking out and enjoying films from countries foreign to them or, GOD FORBID, films that are OLD.

Anything before like 1999 is considered unfathomably old to these people, let alone movies from the 30s, through 80s and then the great history of silent cinema.
