The greatest SF movies never made

I don’t know that I would rush out to see all of these, but I can’t argue with the list of 10 or the reasoning behind it:

10. The “Real” Alien 3
9. The Hitchhiker’s Guide to the Galaxy
8-6. Star Wars Episodes VII, VIII and IX
5. A Doom that isn’t a huge turd
4. Starcraft
3. Snow Crash
2-1. The Matrix Prequel and ONE Sequel
