I think Kubrick just worked with a palette of emotions not often encountered in film.
I've always found 2001 deeply moving. In many of his films he conveys the emotions associated with existential & metaphysical awe & dread. He doesn't give pat authorial answers, catharsis or emotional salves. But when I watch his shit I think "this dude speaks my language". I just get it.
The ambiguity of 2001 has attracted lots of witless, pretentious commentary from blowhards, but I don't think the film itself is pretentious. I think it's fucking beautiful. And haunting.
Funny, I thought 2001 was one of the worst "great movies" ever made. Came out when I was a kid, so never saw it in theaters. After that, you'd have to catch it on TV, since no VCRs yet. Tried watching it at least 4 times, always fell asleep. Once I finally saw it, I was pretty underwhelmed. Found the pacing to be way too slow, and just overall a boring movie. Never tried to watch it again, since then.
Felt the same way about Blade Runner. Never saw it til MANY years after it came out, and was surprised, given its cult status, at how bad I thought it was. After that, I came up with a theory, that any movie or TV show that's dependent on special effects and portrayals of "tech", can't be highly regarded if you don't see it for the first time until it's quite old. Probably why my kids roll their eyes at original Star Trek episodes
I found Jerusalem's Lot pretty scary (first story in Night Shift). The author's foreword in that book is pretty awesome too.
It's a movie that requires a commitment on the part of the viewer to sustained high levels of attention. Were you able to enjoy the first hour of Alien (1979)?
I wasn't born until three years after Blade Runner was released... didn't see it until I was in my 20's... and yet it was obvious to me that it's a masterpiece. I also appreciated how it had clearly been a strong influence on some of what was already my favorite films and media before seeing it. The melding of a film noir aesthetic with a futuristic dystopia is a format that shows up in Dark City, The Matrix, and even my favorite computer game that I loved as a teenager, Deus Ex.
