Still, the way this story unfolds, and how it unpeels its protagonist into a sexually deflowered, master musician is too predictable to be scary, despite a few striking tableaux involving a psychedelic.

If it's psychological horror you love, Nocturne will be music to your ears. If not super-scary, Quirke's film is an accomplished, uncomfortable tour de force.

Nocturne, like its brittle protagonist, is good enough at what it does to make you wish it were a little better.

I found it to be a little convoluted at times, but it recovers with some eye-catching cinematic moments.
