I have all the Buffy seasons on DVD as well as Firefly and the Serenity movie on blue ray....Josh did Avengers too and it was awesome.
He is very character driven...doesn't matter where the characters are or what they do, it's all about their interactions with others and how they react to the normal things in life. Buffy was great because, even though she was a super hero, that was second fiddle to her "real life"
I still like Buffy and Firefly and i'll be 43 in less than a month LOL
