The Sesame Street Muppets return to ABC in a star-filled Christmas special on Sunday December 6 at 3 pm central/4 pm eastern. An Elmo's Christmas Countdown DVD is also available. Since this is the third year the special is airing, if you have seen the special before, post your thoughts on the repeat viewing. One of the true tests of a Muppet production is how well it ages year-after-year. Was it better or worse after repeat viewings? Let us know. Likewise, if this is the first time you've seen the special, we'd love to hear your thoughts as well. What did you like? Let us know your opinions.
