Yet while both Mannis and Haxton served as ‘production consultants’ on The Possession, and Juliet Snowden and Stiles White’s screenplay supposedly takes its inspiration from an article on the box by journalist Leslie Gornstein, this film is true not to the facts of the case, but to the rather different story told by William Friedkin’s The Exorcist.
Calis is especially good as the possessed girl, turning in a performance that can be favorably compared to the gold standard for this kind of role, Linda Blair in “The Exorcist.”
The concept behind The Possession , a solid, Jewish-inflected B-movie riff on The Exorcist from director Ole Bornedal , can't help but leave you wondering.
Unfortunately, it isn’t a comedy, it’s an exorcism-themed horror film that fails to glean suspense out of scenarios that devolved into kitsch after The Exorcist inspired an avalanche of knock-offs that continue to this day.
Like " The Exorcist ," the best film in the genre, it is inspired by some degree of religious scholarship and creates believable characters in a real world.
On the other hand, The Possession is also a horror movie being made in the 2010s, and that puts a serious limit on how much character drama it can hold; once it becomes increasingly obvious that Em is possessed by a demon - a dybbuk, specifically, though the further into Jewish mysticism the movie goes, the more obvious that the writers stuck Jewish concepts into the Catholic framework of The Exorcist , and called that "research" - the film abandons all of its subtlety and becomes yet another generic horror picture of the loud noises, things slamming around, and cheap tricks with dark lighting variety.
