Most critics come away pleased with Jonatan Etzler’s black comedy, and almost all of them say the same thing first: Saoirse Ronan is the reason it works. Her teacher, who locks a disruptive pupil away, is described as grounded, underplayed and sincere, and more than one review ranks it among her strongest work. The premise itself draws admiration for how far Etzler pushes it while keeping the satire on a strained school system in view, and the young cast, Eddie Waller in particular, earns notice alongside her.
The reservations gather around the later stretches, where a number of critics find the plotting pushed past what they can believe. The spread is wide. Screen Daily thinks the early promise fizzles and the film offers little insight for the effort, while The Guardian, the one outright dissenter, finds it heavy-handed and neither shocking nor funny enough, with Ronan its main credit. Variety, otherwise warm, feels the title metaphor is played too broadly.
