While I respect and like to think that I am able to understand his descisions regarding Angel.... The part of the interview that bothered me was the bit about him doing the final episodes of buffy "as a favour to Sarah". Does he not realize that there are a couple hundred other people who work on the show? This just bugged me, sorry.
Also, while I am a huge fan of his, I find the part about him doing it as a favour and it being something he didn't want to do, but still did a little hard to swallow. Again, I really like him, but it's not like he's God's gift to the world... I'm sure the final episodes would have been just as good had he not been there, and personally can't really see why he was. At that point, he wasn't part of the show anymore.
