TV THIS WEEK: Resident Alien lands on SYFY; John Krasinski hosts SNL; Snowpiercer & more

The wait is finally over: SYFY's eagerly anticipated new original series Resident Alien, starring Alan Tudyk as an alien hiding out as a doctor in a small town, lands on SYFY with its series premiere this week. But that's not all!

Along with the debut of Resident Alien on Wednesday, this week also brings the Season 2 premiere of Snowpiercer on TNT (with Wilford's personal train rolling in to cause trouble). If you're looking for some likely sci-fi-tinged comedy, John Krasinski (A Quiet Place, The Office) makes his hosting debut on Saturday Night Live. SYFY also has a new The Movie Show if you want some puppet commentary. Digging a bit deeper, The CW has several new shows this week, including Riverdale, Batwoman and Nancy Drew.

On streaming, Disney+ is leading the charge with a new episode of its high profile, MCU-connected series WandaVision; while CBS All Access has a new installment of its The Stand miniseries. Amazon Prime also has a new episode of The Expanse's penultimate season. There are also plenty of movies on the dial this week, including classics like The Mummy, apocalyptic wackiness like Geostorm, and Marvel faves like Ant-Man.
