Three Dublin lads and their super-smart classmate face an uncertain future in a tale that only hints at dark possibilities

Here is an ensemble coming-of-ager in which someone actually says the line: “That summer may have changed everything …” It’s in a style I associate with the 90s: movies such as Trainspotting or Human Traffic, with people clubbing and yearning and discovering the value of friendship together as the sun comes up. There’s certainly an impressive cast lineup for this one, but there’s also something weirdly formless and frustrating about it as well; the film gestures at some dark and disturbing possibilities in human nature without quite knowing if or how to follow through.

Matthew (Dean-Charles Chapman), Kearney (Finn Cole) and Rez (Ferdia Walsh-Peelo) are three Dublin lads who leave school without much idea of what they want to do – not like their super-smart classmate Jen (Anya Taylor-Joy) who has some ambitious life plans figured out and on whom sweet, sensitive Matthew has a massive crush. But then the boys witness something horrible that shakes them up and reveals a sinister side to Kearney, who has a creepy attitude to Jen and a droog-like enthusiasm for torturing homeless people.
