What are you some underrated or lesser known science fiction movies that you recommend?

I’ve never met anyone that has seen this movie despite it being relatively recent and with some popular actors, but I’d highly recommend Prospect (2018). https://www.imdb.com/title/tt7946422/

It’s not a very big budget movie, but it has great aesthetics I think and an engaging story. I’m looking for some new science fiction movies to watch either old or new.
