TV THIS WEEK: Snowpiercer reaches its stop; new Doom Patrol; plus 'The Old Guard' and 'Palm Springs'

This week we have a few high-profile streaming original movies dropping this week, plus the season finale of TNT's high-concept sci-fi series Snowpiercer. Let's dig in.

The first season of Snowpiercer reaches the station this week, but don't worry, a second season is already in the works. There's also a new episode of Marvel's Agents of S.H.I.E.L.D., fresh off some major twists last week; plus a new episode of The CW's latest super-hit Stargirl. NBC has a double dose of Blindspot, HBO has a new hard-boiled Perry Mason, Fox has a new Ultimate Tag, HBO Max has a new Doom Patrol, and AMC is still creeping us out with NOS4A2.

On the movie front, Netflix is dropping its wild sci-fi fantasy action flick The Old Guard, starring Charlize Theron; and Hulu has its time loop romantic comedy Palm Springs (starring Andy Samberg and Cristin Milioti) going wide. Digging a bit deeper, CINEMAX has the network premiere of the extremely creepy Ma, and STARZ has the network premiere of the new The Grudge flick, if you're a completist on that long-running creep-fest.

Check out our full rundown below and let us know what you'll be watching this week.
