Re: Season 3 is a great season
TOS could be bad, but it was never boring. Disappointing, yeah. Boring, no.
I think you hit the nail on the head here. The reason we still talk about TOS after all this time is because the show was never boring. The various spin-offs could be very entertaining but bad episodes were simply bad and have little to no rewatch value.
