A long time ago when

TV was new (gen 1), you could tag a series show like Dirty Harry, Star Wars, Harry Potter, Star Trek, etc with the same name in the "Show" tag in iTunes and it would occupy one line in the "movies" list in

TV. For example, in that list, one would click "Star Wars" and that would open a list of the 6 movies. It was a GREAT feature so naturally it had to be killed in the "upgrade" to the new OS of

TV 2 and now 3.
It's one of many "just works" features that worked GREAT in gen 1 that still hasn't been resurrected or better implemented in gen's 2 & 3. Of course, back then, our own movies were in the "movies" menu instead of "Computers" and our own tv shows were in the "tv shows" menu instead of "Computers" and so on. But that for-dummies, "just works" intuitiveness had to go too.
Personally, I still wish the last incarnation of that first-gen box could run on third-gen hardware. I still think that version of the UI was the best to date.
