Stylish, eerie and unexpectedly moving by the time of its apocalyptic finish, the strangely titled Good Manners makes for a genuine celluloid surprise.

Was witchhood a vocation in the Middle Ages or, as seems more likely, a charge levelled at sick or troublesome women by superstitious neighbours anxious to be rid of them? One of the merits of the gravely beautiful folk horror film Hagazussa is the way it shows a young Alpine woman of the 15th century committing unspeakable acts not because occult practices run in her family, as the locals believe, but because she is psychotic.

The Frankenstein-style, electrical storm-sparked resurrection of a dead baby in a hospital morgue, and her theft by its creepy attendant, is followed by a homage to Stephen King’s supernaturally potent teenagers, from Carrie to Firestarter, in a threadbare horror with consistent, curious ideas about its own B-movie realm.

It’s hard to feel sympathy for a young man plotting to stove his prospective father-in-law’s head in with a hammer. But when Matvei (Aleksandr Kuznetsov) discovers his quarry is bull-necked cop Andrei (Vitaliy Khaev), this simple plan inevitably suffers violent complications.

Horror has always been a good vehicle for satire, from John Carpenter’s They Live to Jordan Peele’s Get Out. Some metaphors opt for the subtle precision of a surgical knife, and others the hit you over the head. The Platform on Netflix is the latter, a brutal, blunt and effective sledgehammer.

After his two mysterious, tightly-coiled and idiosyncratic first features, Neighbouring Sounds and Aquarius, the masterful Brazilian director Kleber Mendonça Filho lets his hair down with an exhilarating, all-guns-blazing venture into genre.  

Imagine being trapped in your perfect home forever. It’s easy if you try now, as Vivarium’s allegory about property and parenthood is deepened by events.

A creepy lighthouse on a remote island, a blistering storm, a mermaid languishing on the shore and two fabulously bewhiskered actors chewing up the scenery like there’s no tomorrow. The Lighthouse feels like it’s been washed up in a bottle, a film from another time with a story sprung from ghost stories or nightmares.

The 18-year-old Japanese horror hit Ju-On (The Grudge) was remade once before, as – yes – The Grudge (2004), with Sarah Michelle Gellar. Now it's re-rebooted in this stylishly photographed but fatally crass incarnation directed by Nicolas Pesce, who is of the view that if something is scary once, keep repeating it ad nauseam.

Stephen King’s novels have generated an impressive lineage of successful adaptations. This HBO treatment (on Sky Atlantic) of his 2018 novel The Outsider, developed by Richard Price and featuring screenwriting input from Dennis Lehane, is shaping up as one of the best TV incarnations.
