Ok, I'm a big Mistie from way back, so I was all set to start buying all of these like a Star Wars fan who hears a new movie's coming out.
However, Rhino is missing a great chance. First off, having acquired the rights to the movies, they feel compelled to include the original versions of all the movies on the other sides of the discs. That would be great as an extra, except that it limits the box sets to only four movies each. At that rate, the whole run will cost $1500-$2000! Moreover, there are no extras at all! How about more shorts? The Poopie? Making Ofs? Interviews? Commentary, for Chrissakes? Just look at The Simpsons box sets to see how it should be done. Oh, on top of all that, they're not starting at the beginning of Season One or even going in any chronological order at all. It's not even a Best Of based on anything. GRR!
Your best move is to pick and choose your favorite episodes, not to collect all of these as they come out; go for some of the single episodes instead.
