Watch it

“Law & Order: UK” (9 p.m., BBC America). A body of a child is found 25 years after he went missing, and the main witness has repressed memories.

Record it

“Dead Set” (9 p.m., IFC). Surrounded by zombies, the surviving housemates weigh their options in the series finale. Something tells me this ends very bloodily.

“Blue Bloods” (10 p.m., CBS). Danny tries to track down a batch of deadly drugs. Oooh, another very special episode?

Skip it

“The Increasingly Poor Decisions of Todd Margaret” (10 p.m., IFC). I’m so over this, it went from decent to unwatchably bad in a hurry. I don’t mind profanity, but here it’s used as a crutch to prop up lazy writing, and with every character either repellent or unfathomably stupid, the show has become wholly unappealing. (Did I mention I’m so over it?)
