This special was quite good, I was actually kept interested throughout the episode. Some of the reoccurring jokes were funny, had a good premise for an episode, and made some absurdist humor that isn't often seen in South Park anymore. Kind of a happy medium of early season South Park and modern topics. And the episode ended on a good song as-well.
The previous specials have been alright, but had been hit or miss when it comes to certain things, such as pacing, and overall plot. In my opinion, this special did a lot better at those two things. Good plot, and good pacing.
The only bad thing about this special was a couple of the jokes didn't land for me, one of the jokes was a little outdated in my opinion. Otherwise, it's decent modern South Park.
