The whole thing is ultimately too in awe of its own characters, respecting them without pushing them, to feel as fresh and sharp as The Muppet Movie; but it compares tolerably well to the early sequels The Great Muppet Caper and The Muppets Take Manhattan ; none of the new filmmakers have Henson's gift for being embarrassingly earnest without coming across as treacly, and there are a lot of places where the movie suffers from an acute attack of the sweets.
Meanwhile, its most receptive demographic consists of adults who probably want something a bit more knowing than, say, The Great Muppet Caper.
The most recent previous feature film in the series, "Muppets in Space," dates to 1999, but the golden era of the Muppets probably ended 30 years ago, in 1981, when the second movie, "The Great Muppet Caper," was released, and the syndicated "The Muppet Show" -- closer to "The Carol Burnett Show" than to any so-called children's program -- went off the air after five seasons of satire, spoofery, slapstick, shtick, songs and guest stars.
A frisky new film showcasing some old pals made out of felt, charm and some kind of genius, the Disney release "The Muppets" overcomes a jaded streak reflecting its makers' nervousness about selling Kermit the Frog, Miss Piggy, Fozzie Bear and the gang to an audience unfamiliar with "Sesame Street" (a Muppets chapter conspicuously left out of Disney's production notes) or "The Muppet Show" or the best of the earlier feature-length films, "The Great Muppet Caper" being my favorite.
