1) “Magnum P.I.” season-finale, 9 p.m. CBS. The Friday-night finales are spread out – “MacGyver” last week … “Magnum” now … “Blue Bloods” next week. (“MacGyver,’ with an 8 p.m. rerun, won’t be back next year; the others will.) In this one, a woman who has no idea why she’s being stalked. Also, friends try to nudge Magnum and Higgins (shown here in a previous episode) together romantically, at a key time: Higgins’ boyfriend, Ethan Shah, wants her to join him on an extended Doctors Without Borders journey.
2) “Plan 9 From Outer Space,” 8 and 9:30 p.m. ET, Turner Classic Movies. Among the legendary bad movies in Hollywood history, this is at the top (or bottom). The movie itself (1959), which is great fun, is at 9:30; before that, actors do a virtual-session script-reading. Many use heightened approaches and Laraiue Newman adds drolly hilarious narration. This is part of the Classic Film Festival, which includes “Wuthering Heights” (1939) at 2 p.m. and a 2015 Sophia Loren interview at 4.
3) “Dynasty,” 9 p.m., CW. Last season ended abruptly because of COVID, so viewers still don’t know if Fallon will have her wedding with Liam. She did have a wild bachelorette party, of course; also, Alexis and Jeff consummated what had previously been a platonic marriage.
4) “Uncle Vanya,” 9 p.m., PBS. Anton Chekhov’s 1898 play has been on Broadway 10 times, but hasn’t been back since 2000. Here’s a London production, adapted by Conor McPherson (a Tony-nominee for “Seafarer” and “Shining City”) and starring Toby Jones. In the midst of a sold-out run, it was shut down because of COVID audience restrictions. Actors stayed for this filmed version.
5) ALSO: “Saturday Night Live” stars are taking over the streaming world. Aidy Bryant’s “Shrill” has its final season on Hulu today – one day after the arrival of Tina Fey’s “Girls5Eva” on Peacock and HBO Max’s “That Damn Michael Che,” a sketch show with many “SNL” people … including Cecily Strong, whose witty “Schmigadoon” is July 16 on Apple TV+. Beyond “SNL” Netflix has “Jupiter’s Legacy” (second-generation superheroes) and “Monster,” based on a popular young-adult novel.
