Sadly, Dan, there's nothing new. Not one extra: these are the <I>exact</I> same discs as anyone who has the six sets already has.
I'm happy to have the show, and the box is "fun", but a part of me kind of prefers the vinyl slipcased digipacks of before: the lenticular TV box is "showcase packaging" as I will say in the half-written review, but the book wallets inside are not the greatest: they look nothing like the book pages in the original ad materials, and the "cut outs" in the pages to help pull them out are not there...you literally have to slide your finger or thump between the "pages" to pull a disc out - tricky with the few double-sided platters.
I was hoping at least for some new extras: even shoving an extra token new disc with either the 1966 feature or even better the LaserDisc extras, would have been enough to tip some fans over the fence. Rand's supplied me with a list of the supplements from the six season sets, and they match pefectly with what's here.
So...it's nothing more than a decent way to pick up the entire 166 episodes in one shot, and at a fair deal, but you'd have to be a priiiiiity big fan to spring that much for a plastic box.
There...saved myself a review!
