This was not the best year for science fiction movies.
When compiling these separate lists, there just was not much on the Best side of the ledger.
As a rule, I have always excluded superhero movies as sci-fi films, even though they could be considered. In fact, Fantastic Four could absolutely be considered a science fiction film. But it is excluded.
We have kept track of the Best Horror Movie (but not the worst). Here is the previous winners:
Best Sci-Fi Movie
Previous Winners: Upgrade, Blade Runner 2049, Arrival, The Martian, Ex Machina, Star Trek Into Darkness, Edge of Tomorrow, Freaks, The Invisible Man, Dune, Everything Everywhere All at Once, Avatar: The Way of Water, Doctor Who Special 2: Wild Blue Yonder, Dune: Part II
Runner-Up: I only have one and it is Bugonia. I did like this film, as it was filled with complete insanity. Companion is kind of sci-fi.
Best Sci-Fi Movie of 2025:

Predator: Badlands
Predator has had a resurgence over the last few years since Prey. The new film Predator: Badlands features a protagonist who is an actual predator. Elle Fanning was great in the film as the synth Thia.
Worst Sci-Fi Movie of 2025…
We do not have previous winners, but we have a ton of runners-up.
Runners-Up: Tron: Ares, Star Trek: Section 31, M3GAN 2.0, 2073, Electric State. Mickey 17 was on the border between fresh and rotten, but I had it just under the positive.
Worst…

War of the Worlds
There will be more to say about this one down the line. This is just a horrendous film. I feel for poor Ice Cube. What chance did he really have. I mean, if only he worked for Amazon Prime!
