Weekend Preview: ‘The Walking Dead’ Fall Finale

The Walking Dead (AMC, Sunday 9 p.m.) — The wall toppled and a whole herd of walkers is pouring into Alexandria in the last episode of TWD until February.

The Knick (Cinemax, Friday 10 p.m.) — A typical night at the theater isn’t usually this bloody, but then, Thackery isn’t usually trying to separate conjoined twins. Also, Algernon finally gets a shot at his 15 minutes.

Once Upon a Time (ABC, Sunday, 8:00) — Hook tries to fight the evil brewing inside him as his quest for revenge against Gold is reinvigorated.

Sunday Night Football (NBC, Sunday 8:20 p.m.) — What could have been the Brady-Manning matchup we’ve all come to know and love is now Brady-Osweiler, which doesn’t exactly have the same ring to it. Pats vs. Broncos on Sunday night.

Madam Secretary (CBS, Sunday 8:30 p.m.) — The words are practically flowing out of Elizabeth’s mouth during her speech at the UN when she’s handed new information that might cause a bit of a problem, considering that they offer an alternate theory regarding the attack on Air Force One, right as she’s ready to publicly blame Russia.

The Leftovers (HBO, Sunday 9 p.m.) — Meg’s story takes the spotlight as we learn about her struggle with loss and her own personal trip to Miracle.

Homeland (Showtime, Sunday, 9 p.m.) — Carrie finally sees Allison as the turncoat bastard she really is. She’d yell it from the mountain tops, but it’s probably more effective to just run and tell Saul.

The Good Wife (CBS, Sunday, 9:30 p.m.) — Michael J. Fox returns as Louis and teams with Alicia and Lucca on a racial profiling case and the cat finally walks right out of the bag about Alicia and Jason.

CSI: Cyber (CBS, Sunday 10 p.m.) — Once the toothpaste comes out of the tube, you can’t cram it back in … unless you’re a hacker who can crack online message boards to delete other people’s comments.
