TV THIS WEEK: 'The Lost Symbol' hits Peacock; SurrealEstate finale on SYFY; LEGO Masters finale; Emmy Awards & more

We have a big series premiere, a couple of major finales, and the 73rd Emmy Awards leading this week — plus zombies, Marvel twists and a tropical paradise of morality tales.

The big premiere this week is on Peacock, which debuts its new mystery thriller The Lost Symbol, based on Dan Brown's best-selling book series about the character Robert Langdon. SYFY has the season finale of horror series SurrealEstate, Fox has the season finale of the most recent season of LEGO Masters, and CBS has the 73rd Emmy Awards (where we'll be pulling for some fan favorite genre TV shows to bring home some hardware).

Digging deeper, Peacock has a new episode of video game-based game show Frogger, AMC has a new The Walking Dead, Fox has the season finale of summer hit Fantasy Island (which is reportedly close to a second season renewal), and Netflix has the premiere of its new original movie Nightbooks. HBO has the network premiere of its new Mortal Kombat flick, Disney+ has a new episode of animated series Marvel's What If...? and The CW has a new Stargirl on tap.
