TV THIS WEEK: The Walking Dead midseason return; Arrow's 150th; new Deadly Class and more

Fresh off a time jump and with a new group of baddies in town, The Walking Dead is looking to shamble back to the airwaves this week and reclaim some hype. Oh, and Arrow hits a milestone that puts it behind only Smallville as far as CW super-shows are concerned.

Yes, The Walking Dead returns with its midseason premiere, as the survivors try to take on the skin-wearing crazies known as the Whisperers. Though it's worth noting the episode actually premiered a week early, on February 2, for subscribers of AMC Premiere. Along with the Dead, The Arrowverse's OG series is celebrating its 150th episode with a quasi-documentary-style episode this week. The rest of the Arrowverse shows are also mostly new, with Flash joining a fight club and Black Lightning still trying to clean up the streets. The 300th episode of Supernatural also drops this week, complete with the return of one of the show's original stars.

SYFY has new installments for both its buzzy midseason shows in Deadly Class and The Magicians, while History drops a new UFO tale with Project Blue Book. Fox is bringing the vampire mysteries with The Passage, and NBC is landing a new Manifest. But that's still not all.

Check out our full rundown below and let us know what you'll be watching this week.
