Human Harmony never had any sense on the show. She just should show in which cicles Cordelia is walking. But the Vamp Harmony had a deeper character and more sense in the show. She had a storyline. She was more interesting. Anyway I didn't got warm with her character.
You should have given a choice for neither. I agree with [MENTION=11238]KellGreen[/MENTION] I really never saw a difference beside in diet and vamp look. Harmony was always just annoying and I could have lived without her character completely.
Vamp, easily. Human Harm was little more than a walking scenery prop; only when she went from "brainless ditz" to "fanged, bloodsucking brainless ditz" did she develop any real purpose in the story (and I much, much preferred her on AtS than on Buffy).
OMG! <3 Vamp Harmony! :j My husband and I have cosplayed Spike and Harmony (vamp) for Dragon*Con twice. We have pictures with James and Mercedes in those costumes (and a picture with Eliza)... I should scan them and post! XD
We actually love Harmony with Spike, as she is the only girl who ever actually cares for him... and she's evil, sure (She can't help that w/the whole 'no soul' thing), but she doesn't wanna be. I mean... She's all good-conciency and whatnot, actually has a heart, ya know? Even if it isn't beating...
