Anyone who reads my posts, knows i am a HUGE Tara guy.....BUT i too voted No....
Like Epo stated, had she remained on the show, or been brought back, Whedon et al, would eventually got around to her and made her change, and not in a good way.
How she left gave way for the season 6 ender(which i love 'i'd like to test that theory' is my fave line EVER), but more then that, she left, with me and others believing she was a pure soul, a true good guy, not a drop of Evil in her(CWDP strengthened that image).
Yes her death made Kennedy accessible, but i can live with that, simply because, Tara was a great character, and i love her and the fact she wasn't a bad guy.....ever.
Though i would have given a bajillion squillion yen(thats probably about £20---hey i'm not rich....) to See one more AU episode.....with Vamp Willow and Vamp Tara!!!!.....ohhh i think i feel a fanfic idea coming on!!!
