1) “Greatest #AtHome Videos” return, 8 p.m., CBS. Alongside lots of dead-serious shows today, we get an amiable trifle. This began as a one-shot special in May, showing how some people used their pandemic time to create videos – funny (including the “Les Miserables” take-off shown here), quirky, sometimes even emotional. That came back for four summer Fridays and now is a temporary series. Tonight, we see a high school principal’s version of M.C. Hammer’s “U Can’t Touch This” … followed by a suprise virtual visit from Hammer.
2) “Great Performances: Now Hear This,” 9 p.m., PBS. When Franz Schubert died at 31, host Scott Yoo says, he left “more than 1500 works, many of them masterpieces and most of them unpublished.” A generation later, Robert Schumann discovered their beauty and began to use them; so did Lizst and Brahms and more. This was a young man’s emotional music, so Yoo, 49, stays on the sidelines, hearing young people perform and discuss it; there are moments of immense beauty.
3) “A Wilderness of Error,” 8-11:30 p.m., FX, rerunning from 11:30 p.m. to 3 a.m. In the 1970s, Americans were fascinated by the Jeffrey MacDonald case. He was an Army doctor who phoned for help; military police found his wife and daughters brutally murdered and MacDonald with lesser wounds. His wife’s father changed from defending to accusing him; so did Joe McGinniss in writing “Fatal Vision.” Now Errol Morris (“Thin Blue Line”) leads an exhaustive and interesting look.
4) Hockey, 8 p.m. ET, NBC. It’s the fourth game of the best-of-seven finals, with the Dallas Stars and Tampa Bay Lightning trying for their second Stanley Cup championships. (The Stars won in 1999, the Lightning in 2004.) Meanwhile, pro basketball has reached game five of the Eastern Conference finals, with the Boston Celtics and Miami Heat, at 8:30 p.m .ET on ESPN.
5) “Utopia,” any time, Amazon Prime. The word moves quickly through these comic-book buffs: Someone has found the missing sequel to a story; this could hold secrets about real life. It does … but in bigger and scarier ways than they imagine. These buffs – who think they know each other, but don’t – are thrust into a high-stakes world. Adapted from a British series by Gillian Flynn (“Gone Girl”) and directed by Toby Haynes (“Doctor Who,” “Brexit”), the opener is violent, but fascinating.
