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).
