The project was a bad idea from the moment it was announced. But it was the name of the network involved that made the news especially dumbfounding.

The idea that CBS, your grandfather’s network — no matter how old you are — would be the home of a series based on, No. 1, a Twitter feed and, No. 2, a Twitter feed with a dirty word in its title induced a shiver. It was as if the programming executives were daring us to take them seriously. You could imagine high-pitched giggles and an extra ration of chardonnay at CBS Entertainment.

The series, “$#*! My Dad Says,” arrives on Thursday night, and it’s about what you’d expect. It’s not unwatchable — CBS being the last broadcast network that enforces a certain level of competence and coherence in its shows — but it’s irrelevant, a wholly generic sitcom so divorced from its source material that you have to pinch yourself to remember it had anything to do with the Internet, or with the world after 1985. It might as well have been based on a greeting card.

If the rights to the title of Justin Halpern’s one-joke Twitter phenomenon (which also spawned a best-selling book) had been sold to a cable channel, the show might have had a structure that reflected its source in some interesting way, and maybe someone like Alan Arkin or Abe Vigoda would have been hired to play the ornery, profane father.
