The first 30 minutes are excellent: lots of intrigue, more questions than answers and it's carried along wonderfully by the relationship between the actresses Maisie Williams (Lydia) and Florence Pugh (Abbie). But when Abbie mysteriously dies, so does the movie. That's not to say it doesn't have the occasional laugh, particularly some superb moments of deadpan comedy from Monica Dolan as the eccentric headmistress, but overall it just meanders, you lose interest in a plot which has no reason to exist other than to provide a structure for the film.
The Guardian describes The Falling as “a non-sci-fi sci-fi, a deadly serious black comedy and a psychological drama in which psychological assessments are beside the point. It comes from the heart of a certain kind of Englishness” Right Ho! I get it! (not)
However, in my honest opinion, Florence Pugh has real screen charisma and I'd be surprised if Hollywood isn't bashing down her door with offers.
