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+.

In this installment of 3 Reasons to Watch, we look at M. Night Shyamalan’s wonderfully dark television series Servant. The show, about a supernatural nanny with designs on an upper-class Philadelphia power couple and their missing baby, attracted an amazing array of directorial talent and some amazing on-screen presences.

Here’s why you should watch all four seasons of this runaway freight train of a show.

Servant, the stellar Apple TV+ show about a supernatural nanny and the Philadelphia family that plays unwitting and unwilling host to her journey, comes to its fiery finale this week.

Leanne must decide who she’s going to serve, and Dorothy decides what her family and life will be from now on. The episode, entitled “Fallen,” serves up a mostly perfect ending to a mostly perfect show.

Although Ted Lasso is amazing and wildly popular, it’s not the only hit show on Apple TV+. A search engine focused on movies and TV released a top 10 list of everything on Apple’s streaming service, revealing which other series also draw plenty of viewers.

Subscribers to the streaming service might use it to find additional shows worth watching.

M. Night Shyamalan returns to the director’s chair for the penultimate episode of Apple TV+’s Servant, his show about a nanny terrorizing a Philadelphia family in their brownstone.

Leanne has Dorothy all to herself — and Dorothy can’t help but notice. A last-ditch rescue attempt is scuttled after Dorothy insists on hearing some hard truths from Sean and Julian, who may not have the upper hand when they’re done.

Though unnerving and quite upsetting, “Awake” stands tall as one of the greatest episodes yet of this outstanding show.

Bad weather, bad omens and bad timing collide on this week’s installment of Apple TV+ thriller Servant.

Sean and Julian attempt a Hail Mary to wrest control of the Turner house away from evil nanny Leanne. And Dorothy’s about to realize there are worse things than being loved too much.

The episode, entitled “Tunnels,” is a sharply directed half-hour of the horror/mystery series, which is the best show on Apple TV+ — and indeed one of the finest things on TV, full stop. It points the way to darker things coming in Servant’s final two episodes.

Apple TV+ thriller Servant heads toward mutually assured destruction this week. Sean and Julian start believing in angels and demons. Dorothy chases down a lead. Leanne is becoming too powerful to even speak to. And a stranger from the past shows up to tell a story that the Turner family does — and does not — want to hear.

It’s a conflicting, confounding and con … ehh very good episode of the show created by M. Night Shyamalan and Tony Basgallop.

Apple TV+’s Servant takes a trip to a backyard zoo this week. The show about the world’s scariest nanny and her burgeoning mystical powers finds the Turner family in the middle of a circus of violence, vomit and vengeance.

The cult members haven’t run out of ideas about ways to get Leanne back, even if Dorothy has. Plus, Sean and Julian have a brutal heart-to-heart. And Bev has a bone to pick with Leanne.

The episode, entitled “Zoo,” is another marvelously unhinged half-hour of television from the best crew in the biz.

Sean and Dorothy throw a party this week on Servant, the Apple TV+ show about a nanny who is more than she seems and the family harboring her. Leanne is starting to notice that her adopted family isn’t being quite as familial and loving as she’d like. And she decides something must be done about it.

As the neighborhood gathers in the Turner household, Leanne plots her own pincer maneuver in a brilliantly directed installment of the best series on Apple TV+.

Halloween comes early this week on Servant, the Apple TV+ saga of a family increasingly held prisoner by the mystic nanny who once threatened to save them from themselves.

On the prowl for zealots, Leanne discovers that the violence inside her can be used for more than necessary evil. Julian and Sean are starting to lose the illusion that they have any kind of control over her, and are beginning to agree with Dorothy that it’s time for the nanny to go. It’s another excellently creepy outing for the Turner family.
