Speaking for myself, I see Her in that philosophical bucket. It hits with folks who like artsy movies, intellectual movies, culturally introspective movies, etc... It has more in common with Eternal Sunshine than Jurassic Park. The kind of movie nobody says is "bad", but plenty of people say "meh not interested." Some of your comments seem to indicate it's more important to the zeitgeist than most folks would agree with.
It depends on how a person would define, "Important to the zeitgeist," I guess.
Obviously, it's not a Marvel superhero movie. But it was a science fiction movie that was important enough to be nominated for an Academy Award, and it won the most prestigious writing award (best original screenplay)- in fact, it racked those awards up. I can't think of a single person (aka, critic) who didn't have it as one of the top movies that year.
I would agree that it is very similar to
Eternal Sunshine; then again, I also think that's another film that, because of the writing, acting, and plot, continue to be relevant.
Who knows? I'm a film person, and I talk to other film people. I thought the particular choice to use
Her was a particularly poor one. Look at the list- Colossal? A Quiet Place? The Endless?* Moon?** Rogue One.***
If someone chooses to take out that movie, out of the ones mentioned, that's definitely a choice.
And it's interesting how one ranks popcorn movies, as well. I mean, I think that Pacific Rim, for a lot of reasons, had continuing cultural relevance that, say, Avatar never did.
*I loved that movie- but more important than Her?
**Again, a good movie, but beyond Rockwell (always good) and the twist, not a lot there, there. IMO.
***Lovely movie. Enjoyed it in the theater. If not the best, one of best SW movies since the original trilogy. Doubt people will care about it in 10 years, but we will see.
