Speaking of which, "beyond sight" is now defined as "down".
I kinda like to think of the Eye of Thundera as sentient, and very reluctant to let Lion-O use it as a crutch. It spends the whole episode trying to get him to just use his head for a damn minute and then finally, in exasperation, just goes, "Okay, fuck it, the answer is DOWN. Look DOWN, asshole. Happy? Good. Now leave me alone."
...weakest episode yet, though I like the hint-dropping on Mumm-Ra and the Eye's backstory, and Panthro carrying everybody.
(Shark: Nobody's fallen in a hole yet, but they DID have a room slowly filling with water, which is similar. It also looked an awful lot like a bit in Thundercubs Part 1...)
Curious how much of The Key of Omens we'll see in the new series -- in the old series it's revealed that you don't actually READ the Book of Omens, you go INSIDE it using another ThunderMacGuffin, meet with a Guardian, and, if you don't have a THIRD ThunderMacGuffin, he will fucking BURN YOU ALIVE. It may be the most terrifying original-series episode, as well as the only third-season Collection Quest ep that is actually any good. Plus it manages to use the old Save-the-Villain bit in a way that it almost works: Mumm-Ra's pitiful wailing as he's roasted really does make you feel bad for the guy.
