A selective critical checklist of notable Monday TV:

Years and Years (9/8c, HBO): "It's been tough this century," muses family matriarch Muriel Lyons (Anne Reid) — and she's not kidding — as Russell T Davies' extraordinary near-future parable of societal collapse reaches its harrowing finale. In 2029, with even the BBC now shuttered under the autocratic rule of Prime Minister Vivienne Rook (Emma Thompson), is there any hope for true (not fake) news and personal liberty? After several episodes of devastating setbacks, the Lyons finally fight back, joining a revolution with hopes of freeing asylum detainee Viktor (Maxim Baldry) and standing up to the troops turning their neighborhoods into walled-off camps. It's a thrilling if somewhat rushed finish.

Plus, Matt Roush weighs in on 'Stranger Things' new season.

Lights Out with David Spade (11:30/10:30, Comedy Central): The latest attempt to find a companion piece to The Daily Show with Trevor Noah brings the snarky ex-Saturday Night Live comedian back into the spotlight, eschewing political satire for broad swipes at pop culture, "Hollywood Minute" style. The show will open with a traditional monologue, but it's mostly a panel show, with Spade trading quips with the likes of (on opening night) scheduled guests Whitney Cummings, Neal Brennan and Erik Griffin.

The Season 15 star is getting honest about her controversial decision.

The Bachelorette (8/7c, ABC): Hallmark romances feel more real to me than this televised hunt for a soulmate, and yet many will watch breathlessly as Hannah narrows the field in the first half of a two-night live season finale. At least they get a trip to Greece out of it before she has to send home one of the finalists: Jed, Peter or Tyler C. (If history is a guide, one of the rejected beaus from this or a former round will get his own season. And so it goes.)
