The commentaries are usually interesting. And it's very disappointing that Amazon sells this set as a the same collection as the former one - but it contains less content. In fact it's even rather misleading considering that they also show the reviews of the 40 disk set as reviews for this set without noting that there's a difference. In fact - currently the highest ranking review says : "I have covered each of the seven season of "Buffy the Vampire Slayer" elsewhere, so here I want to talk about the "EXCLUSIVE, NEVER-BEFORE-SEEN EXTRAS" included on the 40th DVD in "The Chosen Collection" (Yes, the other 39 discs are the same produced for the individual series sets)" - which is totally irrelevant since this disk isn't included !
They always combine reviews even between different formats, lol. The problem is the description changed between Sunday and Monday(after a ton of people ordered). As I said elsewhere the classic bait and switch. I don't believe it was on purpose but it worked out that way.
