YouTubers Blooms and LS Mark (both whom currently have 250k or more subscribers) both called it their least favorite of all 300+ episodes. Many fans consider it at or near the bottom of the barrel. All the same, I’ve seen fans defend it. Fans of this episode do exist. If there’s one “you either love it or you hate it” South Park episode, I think it’s this one.
Side note: To me, it’s a fun, strange adventure with a tense, fast paced third act. Malcolm McDowell’s narration is the icing on the cake. I’d give it an 8/10. Truth be told, I initially had no idea this episode was unpopular, much less a common least favorite.
I thought it was great. I like the idea of occasionally giving the viewers an entirely different experience than they were expecting as a joke. Very Pythonesque.
