Which season? You mean which Star Trek, right? Do you want: 60s Technicolor and skirts; Animated not because it's for kids, but because special effects are expensive and difficult; Androids and friendly Klingons; Frontier space station; One ship alone against an entire quadrant of the galaxy; Time travel and a theme song with words; Tripping through space with the help of mushrooms; Animated, this time for kids; Star Trek, now with more heart; Star Trek: beyond retirement; Star Trek: humor will set us free?
