FOURTH OF JULY CELEBRATIONS - Here’s our big-bang theory: Nothing matches watching fireworks live and in person. But if you happen to be anchored to the couch this year, television has plenty of “oohs” and “aahs” to offer as well. The explosive programming starts with “Macy’s 4th of July Fireworks Spectacular” (8 p.m. Friday, NBC), which has Nick Cannon hosting the festivities from New York City. Among the performers are Miranda Lambert, Hunter Hayes and Lionel Richie. Also on tap: “A Capitol Fourth” (8 p.m. Friday, PBS). It’s hosted by Tom Bergeron, who welcomes, among others, Frankie Valli, Patti LaBelle and Jordin Sparks to the party on the West Lawn of the U.S. Capitol.
SUNDAY: “Last Tango in Halifax,” the British comedy-drama about second chances, returns with fresh episodes. They begin with Celia and Alan (Anne Reid and Derek Jacobi) trying to plan a secret wedding as soon as possible. 7 p.m., KSPS; 8 p.m., KCDT.
SUNDAY: “Reckless” is a steamy new legal drama in which two opposing attorneys (Anna Wood and Cam Gigandet) try to keep the fact that they have the hots for each other a secret as they square off in a sex-scandal case involving members of the Charleston, South Carolina, police department. 9 p.m., CBS.
SUNDAY: Call it the creepiest disappearing act ever. In “The Leftovers,” 2 percent of the world’s population suddenly vanishes in a rapture-like event. Now, those left behind struggle to make sense of what happened. 10 p.m., HBO.
MONDAY: “Under the Dome,” last summer’s big spooky-kooky hit, returns with an episode penned by none other than Stephen King, whose 2009 novel started the whole thing. He’s promising “some scary, mind-blowing stuff.” 10 p.m., CBS.
TUESDAY: “History Detectives Special Investigations” kicks off Season 11 with a new format that focuses on one iconic mystery per episode. Up first: the 1865 explosion of the SS Sultana, a Mississippi steamboat packed with Union soldiers. 8 p.m., KSPS, 9 p.m., KCDT.
WEDNESDAY: The auditions are over and we finally have our Top 20 contestants on “So You Think You Can Dance.” Tonight, they bust their best moves in a two-hour episode. 8 p.m., Fox.
THURSDAY: On “Hell’s Kitchen” the six remaining chefs head to the University of Southern California, home of the Trojans. Why? To prepare a tailgate feast for gluttonous football fans, of course. 8 p.m., Fox.
FRIDAY: We know you’ve been missing those repulsive zombies from “The Walking Dead.” Now is your chance to catch up with the gore fest via a three-day marathon of episodes, fittingly dubbed a “Dead, White and Blue Weekend.” 9 a.m., AMC.
SATURDAY: The fun continues on “Almost Royal” as Georgie and Poppy take in more of the colonies with a visit to Brooklyn’s Williamsburg neighborhood. There, they learn the art of coffee-making. 7 and 10 p.m., BBC America.
