The Muppet Movie is a beautifully constructed film on many levels, is gorgeous, has an amazing message, and we should all own at least one copy. The Great Muppet Caper is just @#$%ing funny.
Leaning on the tropes of movies, movie-making, and doing occasional spoofs (Piggy's Esther Williams tribute), The Great Muppet Caper sings about what it's going to be, and is that - a pretty thin mystery plot as an excuse for Muppet mayhem. And, along the way, makes it fun for them and for all of us, with terrific sight gags, 4th wall-breaking jokes, improvised moments (there's a scene with Kermit and Piggy in the park that cannot possibly have been in the script), and the patented Muppet formula of running jokes that just get funnier as they go along.
The cast includes the recently departed Diana Rigg (we didn't set out to watch a Diana Rigg film, but she's hilarious in this) and Charles Grodin in a star turn as Nicky, Rigg's ne'er-do-well brother. But there's also UK-friendly cameos as well as those for an American audience. John Cleese and Joan Sanderson's bit feels imported from another movie entirely, and I remember thinking it was very funny when I was 6, but now I find it hysterical.
Anyway, this is an ideal one to watch with the kids. Listen to everything the Muppets are saying, especially in throw-away lines. It's like two separate movies for kids and adults, but I think everyone will still like it.
