Apple TV+’s programming slate seems like a crazily oscillating slate of highs and lows. But the highs thus far prove dizzying indeed.

Directors like M. Night Shyamalan, Rupert Wyatt and Kim Jee-Woon, writers like Min Jin Lee, Paul Theroux, Emily Dickinson and Isaac Asimov, high-concept premises and legendary ensembles all meet on Apple’s streaming service.

The result is a collection of art worth signing up for. On the fourth anniversary of the service’s launch, here’s a look at the best shows on Apple TV+.

Looking for your next science fiction binge? Apple TV+ offers some excellent sci-fi series to keep your eyes popping and (more importantly) your brain humming.

Here are our picks for the best science fiction shows on Apple TV+.

The first season of Hello Tomorrow!, the Apple TV+ show about men selling lunar dreams and lies, comes to a close this week in high style.

Jack needs to tie up some loose ends, and he has no plan for what happens when his clients finally get to the moon. His son Joey must figure out who to honor, his mother or his father. Eddie has butterfingers and Shirley has to pay for it. And someone is, at long last, awake.

The season finale, entitled “What Could Be Better?,” is a great conclusion to a great season.

Hello Tomorrow!, the Apple TV+ show about a Space Age con man and the hapless people stuck in his whirlwind, makes a fateful stop at a baseball game this week.

Lunar real-estate salesman Jack Billings goes deeper into his deception now that he’s found a financier with even fewer scruples than he has about cheating people out of their money. And his son Joey, desperate to get through to his dad, decides to finally start trying to put Jack away for his crimes.

Meanwhile, Shirley and Eddie are in deep money trouble and have nowhere nice to turn. And Herb is left picking up after everyone. The episode, entitled “Certain Forces Once Unleashed,” delivers a bracing half-hour of television.

Hello Tomorrow! returns for more Space Age shenanigans — and a brutal comeuppance for one of Earth’s biggest liars. The Apple TV+ show about a guy selling bunk timeshares on the moon finally hits the pause button on momentum to allow a devastating realization to sink in.

Salesman/con artist Jack Billings may be more doomed than he thinks, even as he succeeds beyond his wildest dreams. Shirley and Joey have had enough, Myrtle gets the sign she’s been searching for, Herb makes good, and Jack has to save an old hero in this stellar episode, entitled “The Gargon Mothership.”

Hello Tomorrow!, the Apple TV+ show about a salesman running out of ways to talk himself out of damnation, flies into a panic this week. Jack’s celebrity spokesman goes missing, and if he’s found by the wrong people, it could blow his entire operation.

At the same time, Shirley’s starting to wonder about Jack’s lies, and Joey has just stopped believing him entirely. And when Herb gets a brief moment to shine, he blows it immediately. The episode, entitled “Another Day, Another Apocalypse,” delivers another great half-hour of the show with the most verve and wit of anything on the Apple TV+ lineup.

Hello Tomorrow!, the Apple TV+ show about hucksters selling a place in the sun (on the moon), takes a trip back in time this week as Jack relives some foundational traumas.

Also this week: Shirley thinks she has a way out of the hole that Brightside’s in, while the one that Herb is stuck in gets deeper by the minute. And Joey finds that there is no end to a life of lies once it really gets going.

This week’s offering, entitled “The Numbers Behind the Numbers,” stacks up as a superlative episode of a superlative program.

Apple TV+ show Hello Tomorrow! spirals toward infinity this week, as events move faster than ace salesman and born liar Jack Billings can possibly control.

The members of his sales team — Eddie, Joey, Shirley and Herb — are all desperate to know why their dreams of advancement and retirement aren’t any closer to fulfillment. And their customers are just as curious when they’re finally going to be able to live on the moon … if ever.

This terrific new show hits its groove in this week’s episode, entitled “From the Desk of Stanley Jenkins,” by finding one rut after another for its desperate heroes to fall into.

Hello Tomorrow!, the new Apple TV+ show about a depressed Space Age huckster and his team of dreamer lackeys who are selling the moon as fast as they can, heads into stormy weather this week.

Slick salesman Jack must agree to a big little lie to cover up an even bigger lie, while his colleagues Joey and Herb face romantic crises (and Shirley’s at her wit’s end). Disgruntled customer Myrtle and fraud-buster Lester chase a big lead they must follow to achieve satisfaction.

In the episode, entitled “Forms, Appropriately Filled and Filed,” this retro-futuristic wonder is off and running to the moon.

New Apple TV+ show Hello Tomorrow! blasts back to the future with a pumped-up Space Age pitchman fighting hard to keep his head above water. Actor Billy Crudup, who dazzled us on The Morning Show, puts in another magnificent turn as the Don Draper-style head of a sales team selling timeshares on the moon in a retro-futurist suburban community.

The new series, the first three episodes of which premiere today, has an awful lot on its mind — and only 30-minute episodes in which to say it all. While the delivery feels a little rushed, I’m calling it: Hello Tomorrow! is a special show.
