I agree, "Passengers" is excellent. Incredible imagery!
"The Martian" also is great and it's not very far-fetched or set very far out in the future.
Big fan of the original "Blade Runner", too. Still trying to figure out the "Blade Runner: 2049" sequel.
Of all the Marvel movies, "Guardians of the Galaxy" may be the most fun. The second Guardians movie is okay too, tho not as good as the first. The "Deadpool" movies are also fun, but in a much darker and far bloodier way.
Loved the creativity and dazzling imagery of "Avatar", but the story was very predictable and "preachy". Still worth a watch, if only for the spectacular scenery.
"Silent Running" is another of my old favorites.
"2001 Space Odessey" is a superb classic... though I'm still not sure I fully understand it even after seeing it several times. (Another early Kubrick film, "Clockwork Orange", has clearer messages but can be a difficult movie to watch.)
"Arrival" is very interesting, though it can take a couple viewings to understand what's happening.
I think "A.I. Artificial Intelligence" is a "new classic".
"Minority Report" and "Day After Tomorrow" are among the best Tom Cruise SciFi flicks (depending upon whether you consider the Mission Impossible movies to be SciFi).
"Interstellar" is another excellent film, not just because I find being alone with Anne Hathaway in a small space craft for years a really intriguing idea.
"Twelve Monkeys" is out there for die-hard Bruce Willis fans (and is much better done than the extremely campy "Fifth Element" that Willis also starred in, while that movie's director Luc Besson much more recently did "Valerian: City of a Thousand Planets" that's just as campy but has much, much better special effects.... what a difference 20 years makes: 1997 vs 2017).
I don't think I'll ever figure out "Inception". Can anyone explain it for me?
For a fun romp (mostly), get the "Firefly" TV series and watch it in order (only 14 episodes), then watch "Serenity" the movie that sort of sums it all up. (Though many fans of the TV show are still begging for it to return.)
I hated the idea of "Cowboys and Aliens". Who would try to mix a Western with a SciFi, then cast a Brit like Daniel Craig as a gunslinging cowboy and who the heck let him wear that hat? After a couple viewings I liked the movie a little better. Interesting idea... Why does SciFi have to be set in the future? In fact, one of the very first SciFi books was Mark Twain's "Connecticut Yankee in King Arthur's Court" that was about time travel into the distant past.
Damn, I know I've just scratched the surface here. There are many more great SciFi movies! I've always been very committed fan of SciFi on TV, in movies, in comics (or "illustrated novels"
) or in books. I recall when I was in 5th grade the teacher asked us to bring in a couple of our favorite books to donate for a small classroom exchange library. I brought in Ray Bradbury's "Fahrenheit 451" and Ayn Rand's "Atlas Shrugged". My teacher asked if I'd actually read them. Yes, I had, along with lots of other SciFi books. At the time I didn't see why she was surprised. I guess the typical 10 year old was reading something else, but none of the other 5th grader books in our little library ever interested me.
