Top-notch TV returns with the sixth and final season of “Better Call Saul” (AMC, 9 p.m.), the prequel which will have to connect with the start of “Breaking Bad.” Already Jimmy McGill is turning into Saul Goodman even as he and Kim (Rhea Seehorn) find a new way to work together. A whole lot of menace is found amid the cartel runners as well. With its unusual low angles and fine photography, “Saul” is a show that can run several minutes without dialogue (despite Saul’s yappy nature). It’s clear the show runners are getting better and better at making great TV, while the actors slightly undermine the story by looking older now in the prequel than they did in the main series.

Having made $750 million at the box office since its release just last month, “The Batman” (HBO Max, streaming) seemingly has nothing to lose by quickly becoming available on a streaming service.

Sam and family go to England on “Better Things” (FX, 10 p.m.).

The finale of the documentary series “The Invisible Pilot” (HBO, 9 p.m.) may or may not answer every question.
