A selective critical checklist of notable weekend TV:

Silicon Valley (Sunday, 10/9c, HBO): Throughout six seasons of inspired tech-world satire, the nerdy geniuses behind Pied Piper have always managed to snatch defeat out of the jaws of success. But with their biggest launch looming in the series finale, could these bumbling heroes finally make it after all? An existential crisis, and something Jared (Zach Woods) calls “the most courageous act of cowardice I’ve ever seen,” contribute to a bittersweet and clever sendoff to one of HBO’s all-time-great comedies.

The list ranges from heart-warming comedies like 'Schitt's Creek' to the beloved 'Supernatural.'

Madam Secretary (Sunday, 10:30/9:30c, 10/PT, CBS): Having finally and thankfully put the fictional impeachment inquiry behind them, the McCord administration takes a victory lap in the series finale of the political drama. As President Elizabeth McCord (Téa Leoni) kicks off a new initiative with a boost from the champion U.S. Women’s Soccer team, the First Family gathers for a long-awaited celebration. Guest stars include a number of former cast members, plus Cicely Tyson as a woman born the day women got the right to vote, Tyne Daly (brother of series star Tim) and singer Peter Frampton.

Supergirl (Sunday, 8/7c, The CW): Launching the network’s most extensive superhero crossover event to date, “Crisis on Infinite Earths,” Supergirl (Melissa Benoist) teams with a multiverse of heroes — Flash (Grant Gustin), Green Arrow (Stephen Amell), Batwoman (Ruby Rose), White Canary (Caity Lotz), The Atom (Brandon Routh) and Superman (Tyler Hoechlin) — to save their worlds — yes, worlds — from imminent doom. The action continues Monday on Batwoman (on a special night, 8/7c) and Tuesday on The Flash (8/7c) before concluding after the New Year on Arrow and DC’s Legends of Tomorrow.

Watchmen (Sunday, 9/8c, HBO): Have your jaws recovered from dropping after last week’s revelation that Angela (Regina King) has been cohabiting with… the omnipotent Doctor Manhattan, who’s been cloaking his mighty blue self in ordinary — if buff — human disguise (Yahya Abdul-Mateen II)? In the penultimate episode of Damon Lindelof‘s dazzling and endlessly provocative fantasia on heroism amid the darker undercurrents of the American character, much will be revealed about the iridescent Doctor’s relationship with the Vietnam-born Tulsa crimefighter. There’s a ton of exposition to stimulate the Watchmen cultists, but also enough wit, suspense and climactic action to enthrall the rest of us mere mortals.

From a shared intellectualism to a desire to save humanity, there are a lot of similarities between the two.

The SpongeBob Musical: Live on Stage! (Saturday, 7/6c, Nickelodeon, TeenNick, Nicktoons): Revel in some high-spirited Broadway magic, and the fanciful Tony-winning scenic design of David Zinn, in a recreation of the tuneful SpongeBob Musical stage show, filmed in front of a live audience. Tony nominees Ethan Slater (a pitch-perfect SpongeBob) and Gavin Lee (a wonderfully dour Squidward, whose multi-tentacled tap dance is a show-stopper) reprise their roles, and joining the cast from the animated series is Tom Kenny as Patchy the Pirate, singing an original Sara Bareilles song, “Poor Pirates.” Even grown-up might be enchanted by this pop-rock extravaganza for all ages, smartly directed by Tina Landau.

Work in Progress (Sunday, 11/10c, Showtime): This exceedingly offbeat slice-of-life comedy stars, and is cowritten by, Abby McEnany, playing Abby, a self-described “fat queer dyke” from Chicago who, at 45, is “sick of struggling” and has declared a 180-day deadline to turn her life around. Or else. Perfect timing for this insecure neurotic to catch the eye of the considerably younger Chris (The Politician‘s Theo Germaine), a trans man who disarms Abby with attention and affection. Could this relationship be real? Stay tuned for an amazing cameo by former Saturday Night Live star Julia Sweeney, whose androgynous character of Pat is something Abby swears ruined her life.
