I really liked this special a lot. I think it was because original Muppet writer and director, Kirk Thatcher, was onboard. Kirk really knows how to write good Muppet stuff.
And I liked how Gonzo was the main character, mainly because they didn't use him much lately in the past.
It was great hearing Brian Henson as Sal again.
I liked how the owner of the mansion said there were 999 ghosts. I can just picture 999 familiar looking characters in that mansion. Minus Gonzo and Pepe, since they were just visitors.
The only problem was that they broke tradition and instead of airing it on basic TV, like all of their other Muppet stuff, it was on streaming. I guess that's the new thing for Muppets?
