School daze

Yara Shahidi often talks directly into the camera in “Grown-ish,” an appropriate choice since the former Minnesotan is fast becoming a spokesperson for her generation. Her character, Zoey Johnson, whom we first met on “Black-ish,” is far from a role model, which is one reason this college-based sitcom has such appeal. In many ways, this is the spinoff that “A Different World” wanted to be, but never quite had the guts to follow through on.

Space, the frightful frontier

“Star Trek” fever comes with a severe case of the chills in the most riveting offering from a new pack of “Black Mirror” episodes. In “U.S.S. Callister,” Jesse Plemons plays a lonely nerd whose fantasies about being Capt. Kirk take a dark turn when he steers his ambitions into a high-tech video game. Cristin Milioti, so terrific in “How I Met Your Mother” and “Fargo,” keeps her hot streak alive in the role of a shanghaied crew member determined to live long and prosper.

“9-1-1” proves a standard procedural can be taken to the next level with the right actors and writers. Ryan Murphy’s team does the heavy lifting behind the scenes, making the daily routines of paramedics, firefighters and cops appear as never before on screen, while Peter Krause, Angela Bassett and Connie Britton dive into the material as if they’re in the running for Emmys. They probably aren’t, but “9-1-1” will keep your heart pounding, a rarity today on network TV.
