Some of those are pretty good.
After having watched parts of both "Solaris" and "Event Horizon" over the weekend, here's one I didn't see on the list:
A space ship or station is invaded by some mysterious force/entity that causes everyone to have terrifying visions of the past/the future. This causes everyone to behave insanely and for some reason all refuse to tell each other what they experience, making it much more difficult to figure out what's going on.
And inspired by other things on the Sci Fi Channel this week:
A scientist researching some new medical technology uses an unwilling human guinea pig to test his new technique/medication, with disastrous results.
The victims of the alien invasion can figure out how to use alien technology easily, or how to use Earth technology to control/destroy alien technology.
Everyone in the post-apocalyptic future still knows history really well, and all are literate. Canned food lasts forever, cars and airplanes still work, and gasoline is easily acquired.
