I probably prefer TOS the least, for one because it is so very campy.
If you can’t appreciate camp, stay out of the campsite.
And most of the campiness of the show is in season three. But there’s still a lot there.
Spock’s Brain remains one of my favorite episodes of the entire franchise.
FTFM
FTFY
What?! No.
My favorite episode is Deja Q, where Q loses his powers.
I like all of the Star Trek series (except Discovery).
Enterprise included?
Yes. Also, Enterprise was renamed Star Trek: Enterprise at the beginning of season 3. So to a degree, the question answers itself.
I just thought most people disliked it and maybe you forgot about it. I’ve never seen it.
My understanding, from this thread, is that most people hate on Enterprise because most people couldn’t watch it, because it aired on UPN which, in many places, wasn’t available.
