You half expect co-writer, executive producer and star Jason Segel to burst out of his character, stare directly at the camera and say: "Gotcha! I had you going there, didn't I?"
That never happens, of course. But you soon get over the absurdity of it all, once the daffy characters go about their wacky business.
Puppet Walter (voiced by Peter Linz), his brother Gary (Jason Segel) and his girlfriend, Mary (Amy Adams), visit Muppet Studios, only to find it a shadow of its former glory.
They uncover a plan by the scheming oil baron Tex Richman (Chris Cooper) to dismantle what's left of the studio to dig for oil. Walter takes it upon himself to trot across the globe to reunite the gang - Kermit the Frog (Steve Whitmire), Miss Piggy and Fozzie Bear (both Eric Jacobson), Gonzo (Dave Goelz) and others who have gone their separate ways.
Gags (sometimes a little rough around the edges) are generated at The Muppets' own expense. They manage to reflect on their decline over the years and laugh about it.
Leave reason and logic at the door. You'll be rewarded with a clever, funny and entertaining film that your parents will drag you to see. Now, there's a first.
