The gotchas are grand, the production design creepy and the undead as undead as ever in Indonesian horror maestro Joko Anwar’s “Satan’s Slaves: Communion,” the sequel to his 2017 zombie hit.

The writer-director took care to not forget the fun in this jumpy, jokey follow-up, the first Indonesian film ever made to fit on IMAX screens.

The cursed family of the first is back, chased into a remote, rundown high-rise on the outskirts of Jakarta. But they are, of course, much reduced in number. “Satan’s Slaves” almost halved their number, with factory worker Rini (Tara Basro), her teen brother Toni (Endy Afrian) and younger sibling Bondi (Nassar Annuz) losing a brother, grandmother and the singer-mother who seems to be the font of all their woes.

A deal with the Devil, you say?

A prologue re-introduces journalist turned “Supernatural Magazine” publisher Budiman (Egy Fedly) and tells us how he crossed over into his specialty, stumbling into the undead way back in 1955.

The “present” here is April of 1984, and our embattled, on the lam family may know there’s always trouble close by. But everybody else in the Mandora apartments is in the dark, soon quite literally as a storm bears down and floods all around them and knocks out the power.

Things start to go wrong before the first rain drop falls. And thanks to some heavy-handed foreshadowing, we know better that to get into that damned elevator.

Anwar stages his first set piece in that over-crowded lift, imperiling not just the people riding in it, but the children who jump into the ground-flood shaft to pick up coins they see have collected there thanks to an accidental door-opening.

The bodies from this debacle are prepared by their families — or other observant Muslims in the building — and lie in their apartments awaiting funerals that will have to wait until the storm passes.

“Why is this building so quiet, all of a sudden?” (in Indonesian with English subtitles).

Anwar uses the flickering match-light and gathering gloom and water to set us up as Toni is summoned to “check on” the prepared corpses with Mr. “You have nothing to fear, just trust in Allah” (Kiki Narendra). Funny how Ustad Mahmud gets a sore back midway through this creepy duty and begs off.

Toni suddenly discovers a gift for massages, pleading, anything to keep this alleged adult from ditching him to check on the dead, which are anything but “quiet.”

There’s a cute, sassy neighbor (Rata Felisha) that the boys all joke must be a “hooker” who needs saving from all the dead who aren’t really dead, and the undead from the first film who return for cameos.

The scale may be bigger than the original film, but the tagline for the sequel is “just fun enough to get by.” The acting is pretty good, and by that I mean the players let us think they’re terrified. It’s somewhat predictable, and the finale is one of those “Let’s over-explain this and maybe set up another sequel” let-downs.

But the jump-frights pay off, the effects are excellent and the zombie makeup even better. And there’s something to be said for the novelty of it all. It isn’t every night-of-the-living-dead spawn that’s built around the Islamic way of death.
