The-Victim-1Kelly Macdonald, who is always pretty great, stars in a new four-part limited series “The Victim” (BritBox, streaming) that may give higher prominence to the anglophile streaming service created by BBC and ITV. She plays the mother of a murdered boy accused years later of leaking the name of a suspect (James Harkness). Who is the victim? A detective played by another reliable UK actor, John Hannah, is trying to find out.

Also online, Kate Bosworth stars in a new sci-fi series “The I-Land” (Netflix, streaming), about 10 people who find themselves in a mysterious land and don’t know how they got there. Alex Pettier and Natalie Martinez are also featured in the seven-episode season from Neil LaBute, who created “In the Company of Men” based on his own play, as well as directing “Nurse Betty,” “The Wickerman” and the Syfy series “Van Helsing.”

The third Democratic Presidential Debate (ABC, Telemundo, 8 p.m.) is on a single night for the first time, but still has ten candidates. Joe Biden and Elizabeth Warren will be on the same debate stage at the same time for the first time, along with Bernie Sanders, Pete Buttigieg, Julian Castro, Amy Klobachar, Andrew Yang, Cory Booker, Kamala Harris and Beto O’Rourke

Emma Stone narrates a new science series “The Mind, Explained” (Netflix, streaming).

A second season starts for the amusing hit man saga “Mr Inbetween” (FX, 10 p.m.).

Also back for a second season is “This Close” (Sundance, midnight), the unique comedy about two deaf friends, one of whom is engaged. Shoshannah Stern and Joshua Feldman are the creators and stars.

The live eviction between Tommy and Holly may end up in breaking up the season’s longest lasting showman on “Big Brother” (CBS, 9 p.m.), leaving the final four. The reduced cast has certainly made “Big Brother After Dark” (Pop, midnight) a much more boring show.
