The Jim-era sets would integrate Kermit and company into our world. That lent a legitimacy that transcended the TV nature of TMS. Since MCC, the sets have catered to the Muppets in a way that created a kind of muppety world. It has nothing to do with actual content or scripted elements. It's the production design. That Oscar category that most people don't quite understand. I wouldn't make that particular claim for TM. The digital film stock, flat lighting and color saturation are responsible for the tinge of artificiality. It didn't overwhelm the film. Still, I hope they find a way to give the new movie more of an authentic film look in post production.
