TV THIS WEEK: The Mandalorian returns; The Simpsons' Halloween; Archer finale & more

Not even a pandemic can stop the Star Wars franchise. Season 2 of the hit Disney+ series The Mandalorian makes its long-awaited return this week, with Mando and Baby Yoda still on the run out in the far fringes of the galaxy. But that's definitely not the only thing happening this week.

It's Halloween, which means there are plenty of horror flicks, marathons and Halloween specials to catch — led by the slightly delayed "Treehouse of Horrors" special episode from The Simpsons. FXX is also rolling out a Simpsons marathon on Halloween, in case you're wanting to keep that programming going all day. FXX also has the season finale of animated spy-fi series Archer, in case you're looking for a bit of Halloween counter-programming.

Digging deeper, Fox has a new episode of neXt; NBC has a new American Ninja Warrior; The CW has a new Supernatural; CBS All Access has a new Star Trek: Discovery; Disney+ has a new episode of The Right Stuff; and AMC has a fresh slate of The Walking Dead spinoff goodness. There are also some horror-friendly movies on tap, with HBO debuting the Black Christmas remake; SYFY defrosting Jason X; and a whole lot more.

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