I LOVE this show! And I like all the characters. ^^
Buffy was very cool. ^^ She had a lot of spunk and I could kinda relate to her (cept for the deamon killing part.

)
Willow was probably my favorite character. She's the one I could relate to the most. ^^
Xander was SOO funny. His character kept me laughing so much!
Faith was amazing, too. Such a bada..
Anya.. lol. She was cool. A perfect match for Xander. But I was soo sad that they killed her. I was like... "NO YOU DIDN'T! BRING HER BACK NOW!"
Kendra was awsome. ^^ I really wish she had more appearences. XD I loved her accent. lol.
Dawn.. Yep. I liked Buffy's sis. She added a lot to the plot and made a good character.
Giles was amazing! He had his very funny moments. ^^
Angel is addorible. xD I loved the twist of how was Buffy's boyfriend and a vampire. xD
Spike was funny. xD. I thought the little tidbit of romance between him and Buffy was cool. ^^
I know there are more characters, but I'm too lazy to list why I like them right now. XD
My favorite episode was the musical one. ^^ I've only seen it once, but I have the script for it and the music. ^^ (I got it at borders for $10). I remember I woke up at 5 in the morning so I could watch it. XD. The songs where just incredible and the meaning of it was just... amazing. I loved the song "Walking Through The Flame" (That is what it's called, right?)
