The Mandalorian (Disney+, 3:01 a.m.): Whether it’s because the holiday is looming or because they’d rather not share oxygen with The Witcher, this week’s Mandalorian arrives today! Right now! It’s probably out already as you read this! If you’re dying to know what one does after one double-crosses a bunch of double-crossers in the middle of a prison break, “Chapter 7” awaits you. Keep an eye out for Liz Shannon Miller’s recap.
Live In Front Of A Studio Audience (ABC, 8 p.m.): Jimmy Kimmel and Norman Lear’s exercise in nostalgia/TV history/casting returns with holiday episodes of Good Times and All In The Family.
