I really like sci-fi, specially the bits where the aliens whip out guns and shoot at arrogant humans, or the heavy-handed real world allegories, but I never quite got into Star Trek. If it helps, I really liked the first couple seasons of new Doctor Who and some random episodes of the old one, but I'm definitely not looking for some Star Wars space-fantasy stuff.

I tried watching the JJ Abrams's movies (felt like Marvel with a sci-fi skinmask), the new Amazon reboot thingy (was completely lost in a sea of references) and the original series (2horny4me), and neither of them seemed like the same show that most people talk fondly about.

I've seen a lot of references to it here, so I assume it's actually enjoyable to leftist nerds, I just didn't find the good stuff. Any recommendations on where to start?

I also would love other recommendations of other non-reactionary sci-fi film/tv, preferably with politics flowing from the barrel of a gun.
