Star Wars for me! I loved firefly and watched Battlestar Galactica religiously as a kid but I still think my midiclorean count would have high enough if I was tested as a child to go to the Jedi temple
Personally I think Firefly was one of the greatest series made. Far too short lived for my liking. Serenity was amazing too!
I'm a huge Sci-fi nerd. Watched everyone of those listed and Babylon 5 Totaly like the latest Star Trek Discovery too.
Westworld season one was amazing and well written season 2 pissed me off - Doris just went too crazy too quick...
Have to agree another vote for Babylon 5. It was one of the first Sci-fi shows to have a proper linier storyline and even managed to link a later episode to one far earlier without it looking weird. Surprised no Buck Rodgers as well.
