If you're including old sci-fi movies, I like Brainstorm (Natalie Wood's last movie), Final Countdown (w/Kirk Douglas), Andromeda Strain, and more recently, Limitless, Dreamcatcher, The Mist, The Thing, The 5th Wave.
For new flicks....The Shack (2017) is a good one. Didn't think I was going to like it. I did though.
