1) “Agents of SHIELD” season-opener, 10 p.m., ABC. In a summer when the superhero movies have been delayed, we need something. The likable “Stargirl” is Tuesdays on CW; now this Marvel show begins its seventh and final season. The team finds itself in 1931 New York City (shown here), with its ship ready to time-jump at any moment. It must figure out what happened, before the past and future face disaster. To lure us in, ABC has Marvel’s “Thor: The Dark World” (2014), from 8-10 p.m.
2) “Game On” debut, 8 p.m., CBS. At its best, summer TV is loud, flashy and fun; at its worst, it’s just loud. This leans to the good side, as top athletes – Rob Gronkowski and Venus Williams – lead teams. They’re joined by (Bobby Lee and Ian Karmel and guests (Gabriel Iglesias and basketball’s J.R. Smith), trying odd things. Gronk pedals a stationary bike superfast and (with Lee) pushes against the winner of the “World’s Strongest Man” contest. It’s fast and foolish and oddly entertaining.
3) “Mrs. America” conclusion, any time, Hulu. While two shows begin, this richly layered mini-series wraps up. It began with bursts of optimism; the Equal Rights Amendment breezed through Congress and drew quick ratification in many states. Its supporters had starpower – Gloria Steinem, Bella Abzug, Shirley Chisholm and more; its opponents had the steel-willed savvy of Phyllis Schlafly. In the finale, both sides feel betrayed. As an amendment, equal-rights had failed; as a concept, it has kept growing.
4) “What We Do in the Shadows,” 10 p.m., FX. The FX people are a rich source of great TV. Yes, they’ve had virus-related setbacks; the next “Fargo” chapter was pushed back from April to sometime this fall. But they produce the excellent “Mrs. America” directly for Hulu and other shows that air on FX and move to Hulu the next day. “Shadows” is a wonderfully weird show about vampires in modern Staten Island. Tonight’s clever episode has a long-ago assistant (called a “familiar”) suddenly return.
5) ALSO: Two shows conclude – “Grant” from 9-11 p.m. on History (with the previous chapters rerunning as 5 and 7) and “Expedition With Steve Backshall” at 10 p.m. on PBS (exploring the wildlife on an Oman mountain). But overshadowing everything, it’s the first day of HBO Max.In one swoop are HBO shows (“Sopranos,” “Game of Thrones”), cartoons (“Looney Tunes,” “South Park”), comedy classics (“Friends,” “Big Bang”), movies (“Casablanca,” DC superheroes) and originals.
