Why She Sucks

 * 4) Buffy sacrificed herself for her, which she didn't exactly earn.
 * 5) She has a selfish attitude and lacks empathy very often.

Redeeming Qualities

 * 1) She matures a bit in Season 7 onwards.
 * 2) She's not as bad as Kennedy
 * 3) Michelle Trachtenberg always did a great job with the material (plus, in "Once More, With Feeling", she showed off her ballet training).
