Clear eyes, full hearts
Every great sports story has an underdog. "Last Chance U" has an entire roster: one talented football player after another, demoted to the junior college circuit after being cut from Division 1 play for failing grades or arrests. East Mississippi Community College is, as the six-part series tells you, their last chance. MVP honors go to Brittany Wagner, the school's athletic instructional adviser, who not only looks like Connie Britton, but mirrors that actress' no-nonsense principal in "Friday Night Lights": tough, compassionate, dedicated.

A folk legend deserves better than "Joan Baez's 75th Birthday Celebration," a sloppily assembled tribute in which the musician harmonizes with Jackson Browne, the Indigo Girls and Paul Simon.

Losing its bite
The "Sharknado" franchise, now three years old, initially worked because it spent just as much attention destroying the tabloid world's version of national treasures as it did toppling Mount Rushmore, the Gateway Arch and the Grand Canyon, all of which come tumbling down in "Sharknado 4: The 4th Awakens." But what's the good of having new chum Paul Shaffer, Patti Stanger and Wayne Newton pop up if they're there simply to pad the credits? For more on the film, see Sunday's Variety section.
