A buck per cartoon, and they are all top selections? That's quite fair, even disregarding the bonus material. I don't have it but from reading the reviews on amazon, seems like the cartoon fans really like it.
One reviewer complained that some top-notch Looney Tunes aren't included, but that's to be expected. Just like when they reissue the Three Stooges, they won't give you all the best ones in one set - otherwise no one would buy the future releases.
