The comedy comes fast and furious in early episodes, rarely taking a breather, and the comedic hit-to-miss ration favors the hits.

There’s promise in both the flexibility of the “Krapopolis” setup, which allows for a Springfield-like bench of supporting players, and the core cast assembled to carry it.

The Flintstones with gore and raunch, plus a spot-the-mythological-reference game, Krapopolis is a pretty one-joke series: Look at what a random debacle ancient civilization was.

The writing on “Krapopolis” isn’t as sharp as some other Harmon properties, but it’s consistently entertaining. If there aren’t massive laughs, there’s a steady flow of chuckles, and sometimes, that’s all someone needs after a long Sunday.

Colorful palettes reminiscent of “Rick and Morty” and character design not far removed from other Fox animated titles are pleasant, if unremarkable. Jokes are delivered at a rapid clip with a low-to-medium hit rate. The humor itself is winkingly out-of-date.

Through the three episodes sent to critics, it looks bland and the stories it’s telling are bland and, most oddly of all, the thematic underpinnings of the series are bland.

Based on the three episodes made available to critics, Krapopolis doesn’t seem worth all this fuss. It lacks the wit, imagination, and emotional savvy of Harmon’s other series. And other than some inspired line readings by the voice cast, the show lives down to a lament by its main character, who at one point gets a muted reaction to a joke, and says, “I agree: it’s not laugh-out-loud funny.”
