When Elmo’s favorite friend, his beloved blanket, is tossed into Oscar’s trash can, Elmo goes in after it, only to find himself transported to Grouchland, where grouches cut off the flowers and keep the stems and you get put in jail if you ask for help.

The Sesame Street characters all go to Grouchland to try to find Elmo, but by then Elmo is on his way to get his blanket back from mean Mr. Huxley (Mandy Patinkin), who takes everything he sees and has a big machine to stamp “MINE” on everything he takes.

Fans of Sesame Street will love this movie, which has all of the Sesame Street trademarks — subtle puns for the parents, delightful silliness for the kids, and gentle lessons about cooperation, loyalty, sharing, and believing in yourself for everyone, all told with their characteristic warmth, good humor, and kindness. Even Oscar the Grouch admits that Elmo is his friend. And at the few moments of mild tension, Ernie and Bert appear to reassure kids that everything is all right.

Patinkin and Vanessa Williams (as the Trash Queen) provide some star power, but the real stars are the Muppets (whose colors and textures are wonderful on the big screen), and the audience — who are invited to participate in the movie at crucial moments.

Families will want to discuss their own “special” toys and other transition objects, and why it can be hard to share sometimes. Some children may be concerned that Elmo does not seem to have any parents, and may need some reassurance. And it can be a lot of fun to spend a couple of hours pretending the whole family is in Grouchland!
