I have never really thought of the Muppets as "nostalgia," I'd rather have the pre-1990 shows than the post-1990 shows.
And I think another thing that needs to be considered (I don't even understand what I'm about to say) is what people mean when they want more, oh what's the right term, "productivity" at Henson. I mean when people say Muppets, do they mean "The Muppets" or "The CLASSIC Muppets/Muppet Show Muppets," the "Muppets," as in well, Muppets, or just more stuff out of The Jim Henson Co. (which itself is sometimes referred to as the Muppets).
I mean, here in the US anyway, the only Henson show on the air is BITBBH. Sure "Farscape" is coming for its supposedly last season and Animal Jam and the Fox series are coming next year. I mean, is the main focus the Classic Muppets/The Muppets or actually diversing its character portfolio into more brands like Fraggle Rock, BITBBH, Hoobs, what have you. Are we looking for a bigger Classic Muppet presence (which luckily seems to be happening, possibly a factor in EM.TV keeping a stake) or just a bigger Henson/Muppet presence, like we had with Farscape. If the Creature Shop (supposedly it stays at Henson) could do more fantasy projects, that'd be great. I don't the "Muppets" and "Bear..." need to be the only working brands. And I'm not counting "Sesame Street."
And that's my two cents, and now my wallet's empty...hey that was pretty good.
