The only place I can say (regarding a new show) where JHC failed was that they had TONS of momentum built up for the renewed popularity of the Muppets during MuppetFest and thereafter, and Kermit got a star on the Walk of Fame...but, they're waiting too long, and there will be a lull in the general populace, where there was tons of Muppet-fever (ah!) to capitalize on and now we're going into the down-slope (for the general public, not us freaky Mupheads).
If 2001 or 2002 had held a new Muppet series, they would have been better off...but, they're waiting too long if they wait until 2004, unless they have another MuppetFest which they advertise better or more specials etc.
What do you think?
Otherwise, right now all they're riding on are these fabulous action figures!!
