1. Prometheus
   Noomi Rapace has charisma and this is a story that I can watch over and over again and not grow tired of the package.
2. Chronicles of Riddick
   This movie takes you far from reality to another, dark universe/underverse.  It moves quickly until the final moment when Riddick sits, victorious, but alone.
3. Interstellar
   I like Matthew McConaughey, and Mackenzie Foy.  The story is awesome.
4. The Mist
   Some of the brief imagery toward the end of the film is aweing.  The gigantic creature walking and the earth shuddering with each footstep feeds the imagination.
5. The Crazies
   The remake is a well crafted story and character piece that portrays “small town” life.
6. The THING from another world
   An iconic image of the explorers standing on the ice in a giant circle referencing what lay just beneath the surface.
7. Invasion of the Body Snatchers 1956 & 1978
   I love the eerieness and sense of chaotic panic of the original film.  Kevin McCarthy and Dana Wynter are both excellent together.
8. Predator
   The Casablanca of Sci Fi and two governors of U.S. states.
9. Forbidden Planet
10. Oblivion
11. Edge of Tomorrow
12. Resident Evil
13. Red Planet
14. Dark was the Night
    Another small town sheriff protecting his community.
15. Gattaca
16. Serenity
17. Total Recall
18. Pitch Black
19. Event Horizon
20. Supernova
21. Aliens

NOTE [10/06/22]: I have just re-ordered the above list, with my favorites in the listed order.  Just thought to add “Interstellar” as one of my faves.  And then added “The Crazies” and “Dark was the Night” after wrestling whether they were actually Sci Fi.  [end note]
