Heretic starts slow and talky, veering into philosophical territory as Hugh Grant’s creepy Mr. Reed drills Sisters Barnes (Sophie Thatcher) and Paxton (Chloe East) about faith and religion. But pretty soon, it turns into an utterly gripping escape thriller and supernatural mystery. Some things about the movie will frustrate you, and even more will have you questioning life itself. But there’s no doubt Heretic will keep you on the edge of your seat, maybe even with one of your eyes half closed.

Apart from Hugh Grant singing Creep, which feels etched into my brain, that ending will have you thinking about it for days.
