Sci-fi TV and Film suggestions

While you're lurking here please suggest some sci-fi TV series or films to watch. Add in a sentence or maybe two to sum it up or what you think of it (even if it is criticism, but you're suggesting to watch it). I'll probably add more as I am bored or hiding from trolls too. An easy one to get us started:

 
**Firefly (TV series) - Space cowboys often on the run from the government. Mostly humor with some darker moments and tries to go against conventions and feels different for me to Joss's other work.

>>16 Yuh, of course it's a Brit-made comic... about a stereotypical American gun fucker from the future, go figure.
