What I really like is discovering civilizations, ancient ruins, history, etc. I couldn’t care less for characters involved in it.
I also like mixing sci-fi with well call it fantasy, like Warhammer 40k or Destiny, and also discovering ancient civilization, although now with more mystical twist in it, which makes it even more interesting.
I really don’t like when people are trying to make space exploration uhm… realistic, since they know so little of it, and by extansion humanize to the where it just become silly.
I like Star Trek, StarGate (all of them), and Battlestar Galactica.
I think you are talking about it:
Lol. I must admit that when I watched it (I think I as 6 or 7), that series sometimes really scared me :D.
