A selective critical checklist of notable Tuesday TV:

This Is Us (9/8c, NBC): Even by this show's standards, the timeline is all over the map in an episode that has its best moments in a turbulent dinner party organized by Rebecca (Mandy Moore) a year after Jack's (Milo Ventimiglia) death — which prompts flashbacks to another eventful meal for the then-newly married Pearsons. In a twist on "Guess Who's Coming to Dinner?", Rebecca hopes to keep the peace when young-adult Kevin shows up with new wife Sophie, and college-fresh Randall brings his new crush Beth to break bread. In the present-day drama, Kevin (Justin Hartley) owns the week as he tries to do right by AA pal and war vet Cassidy (Jennifer Morrison), prompting curmudgeonly Uncle Nicky (Griffin Dunne) to remark, "You have strange relationships with people." True, but fans wouldn't have it any other way.

The 'House' and 'Once Upon a Time' alum also talks learning of Cassidy's Pearson connection and what's next.

The Misery Index (10/9c, TBS): The Good Place's Jameela Jamil is the incongruously glamorous host for a down-and-dirty game show with the tagline, "Let's get miserable." Flanked by members of the irrepressible Impractical Jokers troupe The Tenderloins, contestants are asked to rank real-life humiliations — some shown in viral videos, others in headlines — on a scale of 1-100, based on therapists' expert opinions and revealed on a "Trauma-tron" screen. The "three pillars of misery" include physical pain, emotional trauma and lasting impact. None of which apply to this silly comedy game, where embarrassment gets the last laugh.

Plus, they share which miserable experiences may influence their other work moving forward.

Frontline (10/9c, check local listings at pbs.org): A more serious form of misery is the focus of "Zero Tolerance," the first of three Frontline documentaries planned for this season that deal with the immigration crisis. Veteran political filmmaker Michael Kirk reports on how three key presidential advisers and lightning rods — Steve Bannon, Jeff Sessions and Stephen Miller — shaped the president's hardline views on immigration, turning it into a polarizing wedge issue that has sown division and violence while rallying the administration’s base.

The new game show has players place miserable experiences on a numbered scale.

The World Series (7:30/630c, 4:30/PT, Fox): The Fall Classic kicks off in Houston, where the Astros return to the World Series for the second time in three years. They face the wild-card Washington Nationals, who advanced to their first World Series after sweeping the Cardinals. This could be exciting.
