There were parts that were amazing:
I love that it was a girl kicking butt show
I loved the relationships - between Buffy and her friends
and usually between Buffy and her relationships
I (obviously) adored Giles
I liked how Faith came back into play
There were times when I felt the show go off track
There were definitely things I didn't understand - like the monsters at the end being the same that took Buffy ages to kill just one...
But overall it was snarky, clever, funny, exciting, and enjoyable!
