While I'm sure that any Henson announcement automatically equals "never gonna happen" unless it's a kid's CGI show (even then, Doozers only got to our shores via Hulu), a short lived comedy puppet project, or producing crappy movies based on kid's books that weren't even good or expansive enough to be a movie in the first place (zing!), I'll agree what a TP editorial said. Henson needs to make money off of something, and they only have DC, Labyrinth, and FR in their ownership. They fall into the same situation all classic properties fall into. How do they stay relevant for anyone outside of an aging fanbase with their fading interest that they can't get that much money from anyway? The choices are, unfortunately, make a movie or by a stroke of luck their property becomes relevant again and young people sincerely buy their T-shirts and know who the characters are.
That's where it gets maddening. The movie/TV show has to do really well (or well enough) for it to work. And it's always going to alienate the fanbase no matter what, so you're specifically going after a group of youngsters that don't know the property from anything besides parody or the off chance that someone in their family turned them onto it. Look at Lone Ranger. A property that hasn't been relevant for decades, anyone under the age of 50 only knows it from reference and parody. Old folks stayed away from the movie, younger audiences didn't care. yet, when the property is irrelveant culturally, and they make them annoying, floating CGI characters it works kinda well, and somehow the worst ones are more popular most of the time.
