Welcome back to Tune In: our weekly newsletter offering a guide to the best of the week’s TV.

Each week, Variety’s TV team combs through the week’s schedule, selecting our picks of what to watch and when/how to watch them. This week, Discovery debuts its Unabomber drama, and Rob Lowe investigates the paranormal with his sons.

People of Earth,” TBS, Monday, 10:30 p.m. (CRITICS’ PICK)

[This] year, “People of Earth” smartly expands on the histories of all of the alien “experiencers,” and Jeff and his lovelorn co-worker Don (Bjorn Gustafsson) face new challenges from their superiors as well. There may be one or two too many storylines in Season 2 (Nunez and Tracee Chimo’s romantic storyline feels a little thin, for example), but the cast has gelled extremely well. Ana Gasteyer is consistently razor-sharp as the leader of the support group, and Gustafsson and Michael Cassidy, who plays a rogue alien with lizard skin under his regular-bro exterior, never fail to deftly make the most of their scenes. As an FBI agent who begins to investigate a key character, Nasim Pedrad fits right in to the show’s array of slightly obsessive characters. Like everyone else in Beacon, she has messed up in the past and becomes certain that solving a mystery there will allow her to move forward with her life. (Read the full review here)
