What to watch on Sunday: ‘True Detective’, ‘The Walking Dead’

Sunday night is absolutely packed this week with excellent, must-see television. Here’s what you need to watch.

The Night That Changed America: A Grammy Salute to the Beatles @ 8pm, CBS: That’s a long title—could have gone with “why we love the Beatles.”

The Walking Dead @ 9pm, AMC: Your mid-season premiere.

True Detective @ 9pm, HBO: Arguably the best show on television not named Brooklyn Nine-Nine.

Shameless @ 9pm, Showtime: This season has been very meh. Not happy at all. Perhaps this is the show’s last hoorah?

Downton Abbey @ 9pm, PBS: I don’t know anything about this show. In fact, I pronounced it “downtown” for a really long time.
