I cannot disagree more with this attempt to cabin off what is, and what isn't, science fiction.
Her takes place in the future (check).
With technology that we don't have today (check).
The primary theme is using the future to tell us about today (check).
Oh, and one of the characters and a major issue in the plot involved artificial intelligence (check).
I could keep going on, but if that's not science fiction, then I can't agree with you on anything.
The problem with Her isn't that it is not Sci-Fi, but it just doesn't have that much of an impact. What movies has it influenced in their creation? Has it fundamentally changed movie making? Has it even fundamentally affected Science Fiction movie making?
It came and went. That doesn't mean it is bad, it just isn't what meets my definition of "best." especially when we are excluding other movies that actually DID have major influences.
I was pointing out that it makes no sense that a movie like HER made it, but Avatar did not.
There are movies there that I haven't seen (A quiet place, Colossal, Endless, and Annihilation) which may have very well also been better things to point out, but I didn't know them as well as HER. I chose HER because I know the film better than others.
It's not a bad film, and certainly could go on a Best list, but not when they exclude others which I see having a greater appeal, also were critically acclaimed to a degree (Avatar actually won 3 academy awards...and the awards in many ways were similar to ones Star Wars won if that indicates the impact it would have in the future), greater impact, and basically had more that it did with the exception of maybe story and writing...something seems off to me.
But, as I Pointed out, though through snark and sarcasm via a quote...when we really look at the list, there is no basis for what is "Best" or not on that list except basic opinion. There isn't really any other factor except people who voted felt it was "best" in their qualifications and opinion.
PS: Opinion - A prime example for me...science fiction in movies is MORE than just a literary medium. It also has to be a visual and auditory medium, something that includes more senses than just your mind. I have books to engage my mind, and they tend to do a better job (not always, but normally). The way it is shot, the way the music interacts is a LARGE part of what helps me determine what is "best" in my opinions (rather than based on objective measures like impact). This is why Tron Legacy would probably go on my best lists...because it has great visuals and sound accompanying it...even if the story isn't as deep as some other movies. HER may have decent writing, but the visuals and music really just were not meshing perfectly for me.
