Also received Smallville Season Five on DVD. Warner Bros. housed the previous Smallville sets in plastic albums with a page for each disc. The Season Five set was in the annoying fold-out DVD holder that doesn't let you take out Disc 2 without first removing Disc 1, and so on through Disc 6.
This type of case is ill-conceived, in my opinion, but I put up with it. Put up with it until the minor damage that understandably occurs in shipping renders two of the half-notches useless, meaning Discs 1 and 6 will not stay in place in the original holder.
I'm making do with spare CD jewel cases, but a set should be a set, I say.
