"Rm wa V/u" is also a great episode dealing with the troubled life of Cordelia Chase and a crazy ghost to boot.
"I Will Remember You" tugs on the heart strings as Buffy and Angel are re-united once again in the best possible way only to be pulled apart in the worst way.
"Hero" focuses on Doyle's history and a chance for redemption. Extremely well written and very sad I wept buckets!
"Expecting" is also really good as Wesley who has now appeared in the story works with Angel to rescue her Cordelia from a horrible situation.
The series features some wonderful gimmicks, the best being Wolfram and Hart – an evil law firm who is behind much of the chaos and death in the first series. Wesley also becomes a key part of the narrative – losing at least some of his pretentions as he helps Angel on his mission.
I think that Charisma Carpenter also deserves credit because she on one level has the hardest part to play as Cordelia. Initially vapid and cruel in Buffy thanks to Carpenter she is still always inherently likeable even at her worst. Carpenter also shows her acting power through out the series as Cordelia is tortured, tormented and abused through much of the first series.
