HER hasn't been mentioned and deserves to be: an absolutely wonderful film, just without the war and spaceships that most sci fi relies on.
It's been a great 23 years for sci fi:
Minority Report
Children of Men
Dune
Blade Runner 2049
Her
All fantastic.
Finger's crossed for Part 2 of Dune and here's hoping someone does a great new cyberpunk movie now that the game is finally a success. A great version of Neuromancer would be a sweet, sweet thing. Star Wars cannot be redeemed, but I still hold out hope that a new, wonderful Star Trek movie could be made.
