Shows such as “Big Little Lies” and “Fleabag,” presented as standalone stories in their first seasons, came back with fascinating new characters and plotlines for their second seasons.

The episode opens with Marianne Wallace (Cobie Smulders), a botanist coming back from an expedition, sitting at the table by the window with notebooks strewn about, leaves pressed onto the pages.

The episode ends with the two of them watching old footage of “Night Shift,” laughing together as old friends. Two vampires, together for eternity.

This episode is deeply concerned with the uncomfortable and haunting line between adolescence and adulthood.

Episode 8, entitled “No Hospital,” opens with an ailing old man named Mr. Bracamonte (Tony Plana) revising his last will and testament.

In the past two episodes of “Room 104,” a lot of ground has been covered. The show, one that is known for pushing the boundaries of what a series can do, has used this season to explore a more existential type of thriller.

“Watchmen” as a TV show tackles its own repository of social issues and story obstacles set to the familiar background of dystopian disillusionment.

Season eight’s winter may have come and gone, but the Game of Thrones franchise soldiers on with all the mindless determination of an ice zombie dragged shrieking from a frozen grave.

The emotional stress beautifully exhibited by Castro is furthered when, after thinking he solved his illness by discovering he had been “abducted by aliens,” Craig wakes up to realize his skin lesions have worsened and spread.
