MST3K 206: Ring of Terror

There's a new collection of official Mystery Science Theater 3000 DVDs out, and remembering how the previous boxed set stopped being sold pretty quickly due to what I gather was an unexpected problem with rights for one of its movies, I was swift to order this set as well. However, I did wonder a little about the four episodes included in it. It happens that all of them were episodes I got to fairly late in my watching of the series, ones whose descriptions hadn't really grabbed me. Would this, perhaps, be a collection picked up out of a mere push towards completeness, one otherwise "disposable?" The thought came to mind as I started rewatching one of the episodes in it, "Ring of Terror."
