This week, “Supernatural” airs its 300th episode, America’s favorite neighbor is given a backstory, and “The Walking Dead” returns with more human/zombie mayhem.

Dispatches: Weekly TV news
CEO of FX Networks and FX Productions, John Landgraf, announced at the Television Critics Association winter press tour that the upcoming third season of “Legion” will be the show’s last. Landgraf said that series creator Noah Hawley had always planned for “Legion,” which is based on the Marvel Comics, to be three seasons.

Kristoff St. John, the actor best-known for his portrayal of Neil Winters on CBS’ long-running daytime soap opera “The Young and the Restless,” has died at age 52. St. John was nominated for nine Daytime Emmy Awards for his work as Winters, winning in 1992 and 2008.

Yet another reason to watch the Muppets. An episode of “Muppet Babies” has been nominated for the prestigious Humanitas Prize, which recognizes writers whose work “explores the human condition in a nuanced, meaningful way.” Written by Laura Screebny, the episode, “You Say Potato, I Say Best Friend,” where Gonzo becomes best friends with a potato, is about inclusion and recognizing that not all children play the same way.

Contenders: Shows to keep on your radar
Because the charming Jeffrey Dean Morgan guest stars and 300 episodes is worth celebrating, the occult fighting men of “Supernatural” deserve a mention. Their landmark episode airs Feb. 7 at 8 p.m. ET/PT on The CW.

America’s favorite neighbor, Fred Rogers, is the subject of “Won’t You Be My Neighbor?” (Feb. 9, PBS Independent Lens, 8 p.m. ET/PT). Theatrically released in 2018, the documentary tells the story of how a soft-spoken advocate for children wrote and produced a television show that aired daily across America for more than 30 years. The film honestly captures the dedication of this television pioneer, whose work enriched generations of children.

Also on PBS this weekend is “Margaret: The Rebel Princess,” a two-part documentary series that offers an insider’s look at the tumultuous life of Princess Margaret (Feb. 10 at 10 p.m. ET/PT. Part two premieres Feb. 17, 10 p.m. ET/PT). Featuring rare footage and interviews, the film explores how Margaret’s rebelliousness was often unkindly judged by the public and the press but set the stage for a new generation of Britain’s Royal Family.

Archaeologists Blue Nelson and Mike Arbuthnot set out to solve the mystery of “America’s Lost Vikings” (Feb. 10, Science Channel, 10 p.m. ET/PT). The new six-part series explores evidence that Norsemen landed on the coast of North America 500 years before Christopher Columbus.

The post-Rick communities of “The Walking Dead” return for their midseason premiere (Feb. 10, AMC, 9 p.m. ET/PT). A surprising new threat is discovered that will force the groups to unite.

Report Card: A look at ratings winners and losers
Winners: NBC has renewed medical drama “New Amsterdam” for a second season.

Losers: The score may have had something to do with it. Ratings for Super Bowl LIII were the lowest in 10 years.
