Query: Mostly dull and annoying

My son owns quite a few Sesame St DVDs but this is by far the worst one. The dance teacher is dreadful - she has a terrible singing voice, and her speaking voice is pretty annoying too. The plot is very dull and most of the action takes place in a dance studio/classroom. Mostly it shows children, not much of the muppets. The dances themselves don't have interesting moves, and the songs are not at all memorable for their tune or their words.
