News that there's a Labyrinth comic book prequel in the works is nothing to be sniffed at, obviously, but two important questions spring immediately to mind.
First: isn't the whole idea of a prequel to that film kind of missing the point? Given that the crux of it is that it doesn't really matter whether Sarah's adventure was real or not, so much as the process of going through it? And even if it was real, the power of the central metaphor is sufficiently strong that I'd be leery of trying anything else with the franchise once that idea is excised.
Secondly, and far more importantly, if you're going to do a Labyrinth prequel, why in the name of all that's holy are you basing it around Jareth, and not Sir Didymus.
Here, let me show you how awesome that would be:
Plus, you get to call it "The Adventures of Diddy Sir Didymus."
