I recorded all of the Deadwoods to DVD last season and I'm glad I did because the price they're asking is way too high in my opinion. It's a good show though. But another TV Western that I liked even better was Lonesome Dove: The Outlaw Years. You can get those 22 episodes for around $30. Great show, real dark and violent.
The episodes on the set are split up kinda weird. Discs One and Two have two episodes each. Then Discs Three and Four have three episodes each. Disc Five has the last two. And Disc Six has the special features.
It's designed to have a faux leather book cover on the outside. It opens like a book with the actual discs in a case that sits it. That interior part is very similar in feel, look and design to the Carnivale set.
Not sure if that's the most articulate description of it but I tried.
