That's a good point--suspending disbelief vs diminishing the characters. I'd be disappointed if he stayed having amnesia by the end. MTM is a different kind of Muppet movie, no doubt. If you stumbled upon it on TV, in a random non-Muppets scene, you'd probably think it was a grown up '80s comedy. I appreciate that they had enough faith in the Muppets to have them pull off both the gentle social commentary and angsty drama. They were never in an environment that felt that real in tone again. You know, Jenny talks to Kermit like he's a real person. Whereas Tina Fey hams it up like a cartoon villain (or a latter day SNL cast member ).
