It is a little unfair to poor ol' TAS isnt it? Either it should be included with TOS, as its fourth and fifth years, or just omitted for the purposes of this poll. I consider TAS canon (it was on screen, I saw it happen. And its a lot more true to the spirit of TOS than some of the spin offs, and even some of the TOS era movies. I mean, if we go by Roddenberry's word, TOS, TAS, and STV and VI are non canon too). As Picard might say 'THERE ARE. SIX SERIES. AND ELEVEN MOVIES!' :P
The animation may have dated a lot, but the stories are mostly good and may have worked on its live action parent.
