Sesame Street fans will love this sweet movie.
Parents need to know that everything is topsy turvy when Elmo ventures into Grouchland, so a certain understanding of what is (and isn't) acceptable behavior is needed to get the humor fully -- hearing the pleasure with which the Grouches tell each other to get lost is funny only if you know it's not really OK. There are a few mildly perilous/tense moments that could upset sensitive or very young viewers, and some kids may be concerned that Elmo doesn't seem to have any parents and could need some reassurance.
