Broadchurch 10 p.m., BBC America
This eight-episode crime series has a few things in common with “The Killing,” except it’s set in the United Kingdom in a seaside community where it is often sunny. The darkness, alas, is inside a few of the citizens. A pair of very different homicide detectives — David Tennant’s Alec is brusque, Olivia Colman’s Ellie is emotional — work together to solve the murder of an 11-year-old boy. It’s an engaging murder mystery, with a particularly affecting performance by David Bradley (pictured) as the newsstand owner. Bradley was unforgettable as the awful Walder Frey in “Game of Thrones.”

TV Land airs plenty of repeats of this great sitcom, but I’m singling out this episode because it was the first time the show aired without a laugh track. Called “O.R.,” the half hour is set entirely in the operating room, which is overflowing with casualties and Hawkeye’s gallows humor. Nowadays, laugh tracks are in the minority, but back in 1974 the quiet was jolting on a sitcom. Pictured (from left): Alan
