Just finished watching my copy. I think I enjoyed it more on DVD than when I watched it on TV last year. That might be because I already knew what to expect this time. Regardless, I do think it's an enjoyable special, and the extra content is pretty good, small though it may be.
Regarding the recasts, I must say that I'm pleased with basically all of them. Floyd in particular just sounds perfect. He's clearly Floyd, which makes me happy. I still can't hear Rowlf without thinking of Bobo, but those two characters just have similar voices anyway, so it's bound to happen.
Speaking of Bobo, I continue to be amazed at how funny he is in this special! I was pleased with all of his extra screen time during the outtakes! I'd love to see Bobo paired with Nathan Lane again at some point, as their appearances are the best part of the show in my opinion.
