Science fiction, for me, includes well-done special-effects, innovative ideas, and a good story. Perhaps a new world for a setting. Maybe throw in some time travel, or characters who are machines, or some whimsical aliens. I can always get behind whimsy. Really good science fiction, of course, makes little to no sense. Science fiction is exciting. It takes you to new worlds, and the future, and it's lots of fun, and if it's not done well, it's wonderfully cheesy.
I'm so excited.
