Thursday 20“Fringe” (KASA-2 8 p.m.) FOX closes out the second season of its trippy sci-fi drama. Will it return for a third? Eh, maybe.Friday 21Memorial Tribute: Lena Horne (TCM 6 p.m.) TCM honors singer/actress Lena Horne with a triple feature of films: 1938’s The Duke Is Tops, 1943’s Cabin in the Sky and 1942’s Panama Hattie.Zebraman (Sundance 7 p.m.) Japanese madman Takashi Miike’s balls-to-the-wall bonkers 2004 sci-fi flick is both a loving tribute to and a crazed parody of superhero flicks. In it, a failed father tries to escape reality by dressing up as his favorite childhood hero—and is soon called upon to defeat evil alien invaders.Saturday 22“Revolver Golden Gods Awards” (VH1 Classics 8 p.m.) Revolver, the world’s loudest rockmagazine, hands out statues to famed hard rock and heavy metal acts. I’m guessing the black leather pants and skull T-shirt quotient in the room is gonna be through the roof.Sunday 23Seven Deadly Sins (LMN 6 p.m.) Author Robin Wasserman’s sex-obsessed teen lit series gets adapted as a TV mini-series. Think of it as “Desperate Housewives” for tweens.Monday 24“10 Things I Hate About You” (ABC Family 6 p.m.) ABC Family’s short-lived movie spin-off concludes its run with this Season 2 finale.“The Bachelorette” (KOAT-7 8 p.m.) Like the return of the red-breasted robin, the re-emergence of crappy reality shows is a clear indication that summer is upon us.“Law & Order” (KOB-4 9 p.m.) It’s official, NBC has canceled its flagship legal drama, making this 20th season finale the last. Ouch. That means the show is stuck one season short of beating “Gunsmoke” as the longest-running drama in prime-time history. Tuesday 25TCM Spotlight: Race and Hollywood (TCM 6 p.m.) TCM explores the role of Native Americans in Hollywood starting with the 1914 Cecil B.

Gee, I wonder if Kate will drop by for tea and sympathy.Wednesday 26“American Idol” (KASA-2 7 p.m.) “American Idol” ends its comparatively dull ninth season with a 127-minute episode. I guess 130 minutes would have been excessive.“Saturday Night Live Presents: Sports All-Stars” (KOB-4 7 p.m.) Because sports stars are always the most hilarious hosts on “SNL.”
