In terms of new shows, ABC kicks off prime-time soap “Betrayal” (ABC at 10); critic Hank Stuever says it’s “a sleek but forgettable addition to ABC’s undying belief in the nighttime soap.”

Over on cable, debuts include the comedy “Instant Mom” (Nickelodeon at 8:30); “Masters of Sex” (Showtime at 10); and Stephen Merchant’s “Hello Ladies” (HBO at 10).

And finally, the big finale: “Breaking Bad” (AMC at 9) wraps up its fifth (and final) season.
