A half hour ago, a total stranger asked me to recommend some SF films. She said she liked SF, but most films in the genre simply aren't very good (It's true), and she was hoping I could point her at some of the better stuff.
I said I'd do what I could, but for me, SF is at its best when it's a *little bit* crappy, kind of like rock. Make it too slick, and it loses some of its charms. Do you like The Ramones, or do you like Yes? The truth is: I like both quite a bit, but there's an energy to the less polished stuff that the virtuosity of the better stuff can't touch.
