Superheroes seem to be at the saturation point, perhaps because of the impending “Batman vs. Superman” at the theaters. Or maybe they’ve always been around. Either way, tonight there are replays of both “Superman: The Movie” (Syfy, 5 p.m.) and “Batman Begins” (TNT, 8 p.m.) as well as last year’s “Avengers: Age of Ultron” (Starz, 6:35 p.m.) and its predecessor “The Avengers” (FX, 7 p.m.). A character named Cupid kills couples on their wedding days on a new episode of “Arrow” (The CW, 8 p.m.), one of several prime time superhero shows.
And the hype extends to Turner Classic Movies, which in its honor of “Superman vs. Batman” presents some of the early serialized treatments of those comic book heroes, and others, largely from the 1940s. It includes “Batman: The Bat’s Cave” (8 p.m.), “Batman and Robin: Batman Takes Over” (9 p.m.), “Superman: Depths of the Earth” (10 p.m.), “Atom Man vs. Superman: Atom Man Appears” (10:45 p.m.), “The Green Hornet: The Thundering Terror” (11:30 p.m.), “Buck Rogers: Tomorrow’s World” (12:30 a.m.), “Flash Gordon Conquets the Universe: The Purple Death” (1:30 a.m.), “The Phantom: The Sign of the Skull” (2:15 a.m.), “Ace Drummond: The Invisible Enemy” (3:15 a.m.), “Dick Tracy: The Spider Strikes” (4 a.m.) and “Dick Tracy” (5 a.m.).
Elsewhere, “Younger” (TV Land, 10 p.m.) reaches its second season finale, Liza wonders whether her ploy at pretending to be 26 has been worth it, especially after a tragedy.
After last week’s doozie of an episode at the DMV and with the Democratic front-runner, this week’s “Broad City” (Comedy Central, 10 p.m.) introduces Tony Danza as Abbi’s father, living in suburban Philadelphia.
“Heartbeat” (NBC, 8 p.m.), which premiered Tuesday, settles into its regular timeslot with an episode about conjoined twins with cancer.
“Little Women: Atlanta” (Lifetime, 10 p.m.) closes its first season with a reunion special — something expected in reality shows. But it will be unusual when the cast of “Young & Hungry” (Freeform, 8 p.m.) forgoes its episode tonight in order to take questions from the studio audience.
David Copperfield inspires Adam to be a magician on “The Goldbergs” (ABC, 8:30 p.m.).
With the Brawn team decimated, the merge happened a little earlier than expected last week on “Survivor” (CBS, 8 p.m.). They’re still adjusting.
The family takes a trip to Mammoth Cave on “The Middle” (ABC, 8 p.m.). But on “Modern Family” (ABC, 9 p.m.), Phil and Claire go to Paris.
Paige shares a secret on “The Americans” (FX, 10 p.m.).
On a new “Nashville” (ABC, 10 p.m.), Luke asks Riff Bell to go out on tour with him.
The missing organ urban myth pops up again on “Criminal Minds: Beyond Borders” (CBS, 10 p.m.).

In the NIT men’s college basketball quarterfinals, it’s Florida vs. George Washington (ESPN2, 7 p.m.) and San Diego State vs. Georgia Tech (ESPN2, 9 p.m.).
In the NCAA Division II women’s college basketball semifinals, it’s Lubbock Christian vs. Bentley (CBS Sports, 7 p.m.) and Alaska Anchorage vs. Grand Valley State (CBS Sports, 9:30 p.m.)
Spring baseball includes Tampa Bay vs. Minnesota (MLB, 1 p.m.), Washington vs. Yankees (MLB, 5 p.m.) and Oakland vs. Seattle (MLB, 10 p.m.).
