Two young missionaries are forced to prove their faith when they knock on the wrong door and are greeted by a diabolical Mr. Reed, becoming ensnared in his deadly game of cat-and-mouse.

Hugh Grant has infectious fun playing against type in Heretic, a religious horror that preaches the gospel of cerebral chills over cheap shocks.

As the titular Heretic, Hugh Grant and his theological musings are as irresistible as blueberry pie, even if the story’s payoff doesn’t quite reach its biblically good setup.

'Heretic' is a thought-provoking film exploring faith and control, featuring Hugh Grant's standout performance. The intelligent dialogue and atmospheric tension are praised, especially in the first half. However, some find the second half less compelling as it shifts to conventional horror, losing initial depth. The ending is contentious, with mixed reactions to its predictability. Despite criticisms, the film is appreciated for its premise and performances, though it may not satisfy pure horror enthusiasts.
