Eschewing fussily prepared three-act structures and stopwatch-timed story beats, Dario Argento’s films unfold according to their own distinctive logic.

Between shots of stunning mountain scenery there are paranormal breezes, unfeasibly bright night-lighting and buckets and buckets of maggots.

The best acting is by an expressive, resourceful chimpanzee -- definitely the year's Best Supporting Primate.

While an uneven Argento film, Phenomena still manages to provide plenty of style and deliver a worthy look at the horrors of growing up.
