1) “Brooklyn Nine-Nine” finale, 8-9 p.m., NBC. “Nine-Nine” (shown here in a previous episode) started hot in 2014 – Golden Globes for best comedy and comedy actor (Andy Samberg), Television Critics Association nominations for best comedy and new show. Then things got bumpy: Fox cancelled the show after five seasons; NBC aired two more full seasons and this 10-episode summer one. After tonight, NBC heads into a fall line-up that will mostly be laugh-free in prime time.
2) “The Lost Symbol” debut, any time, Peacock. Three Ron Howard movies have had Tom Hanks as Robert Langdon, an expert on ancient codes and puzzles that unearth modern plots. Now this series – with Howard as one of the producers – has a younger Langdon (Ashley Zukerman, 37) on the Harvard faculty; he’s nudged into this world in ways that are alternately fascinating and just creepy.
3) More streaming. Hulu launches “The Premise,” a five-week anthology. That starts with “Social Justice Sex Tape,” which is quite clever and (you might have guessed from the title) quite adult. Paramount+ counters with “The Harper House,” a fairly good animated series for grown-ups: With her finances crumbling, Debbie Harper moves her family into her late aunt’s house – an ominous place in a maybe-sketchy Arkansas neighborhood.
4) “Mary Poppins” (1964) and “Matilda” (1996), 6 and 9 p.m., Freeform. Two great family films – one heralded, one not – go back-to-back. “Poppins” won five Academy Awards (including Julie Andrews for best actress) and was nominated for eight more (including best picture). “Matilda” received no such attention, but is a terrific film. Danny DeVito, directing and co-starring, captured the dark humor of Roald Dahl’s tale of a little girl (Mara Wilson) finding special powers in a cruel world.
5) “Coroner,” 8 p.m., CW. Medical examiners use a “body farm” to study decay under different conditions. At this one, however, Jenny makes a gruesome discovery. Also, her father, in the early stages of Alzheimer’s, continues to court a mysterious woman.
