Can anyone tell me if the "Wild at Heart" commentary from S4 is any good? I'm an Oz fan, so missing out on this is very frustrating.

I've had the R2 set a while and I love Joss Whedon's commentarys, but I cannot justify spending $40 for the same boxset for one commentary, (also philistine that I am I prefer the widescreen).

So is it any good? and is there anywhere where I can buy it or even download it?

I just listened to the commentary and it's hilarious. There are some major spoilers for season 6. Can't tell you if I think it's worth $40 but I really enjoyed it.

Yeah, spoilers abound on the Buffy 4 set. The menus are rife with them, they're all over the commentaries and the featurettes have their share too.

What are the eps. with commentaries in the Buffy and Angel sets anyway?
I listened to the aforementioned one in this thread and found Whedon and Co. to be quite entertaining on the mic, so ones with Whedon involved are preferred!
