With its new reality series “Chasing Farrah” (9 p.m., TV Land), the nostalgic network appears to be chasing a younger, hipper audience. Good luck to them, and to anybody of any age trying to make sense of “Chasing.”

The good news is that “Chasing Farrah” is not entirely vulgar or completely depressing like the car-wreck vanity vehicles featuring Anna Nicole Smith or the Gastineau, Gotti and Grubman entourages. The bad news is that this leaky Fawcett feature leans toward the baffling and pretentious.

Like every show of its kind, “Chasing” invites us into Farrah’s “real” world, the life of a celebrity best known for a pinup poster popular during the Ford administration. Accosted by fans and photographers at every turn, Farrah decides that a reality-show camera crew would be but one more layer of media interference. But since Fawcett considers reality shows “phony,” she insists that there be a camera crew to document the camera crew. And she often points her digital camera at the dueling crews just for good measure. The proliferation of lenses provides the producers and editors with a wealth of footage for a show within a show about not much at all.

“Chasing” takes celebrity self-absorption to new and unexpected places. And, in the end, this exercise in frenetic editing culminates into a cubist nightmare, collapsing past and present, myth and nostalgia into a single sad experience — the sunlit moment when the eternal sex symbol stumbles toward senility.
