Matthew Dunseath’s review published on Letterboxd:
Young offender Eric (Jack O'Connell) starts his first day of adult prison life, in manner as explosive as his alleged behaviour that got him 'starred up' from juvenile hall in the first place. What the fiery young man didn't anticipate was butting horns with his long-serving father Neville (Ben Mendelsohn) in the same jail. Within the stone cold walls the two men encounter men, stripped of their normality, taken away from civilisation and resorting to the mindless regime, governed by an unfair staff.
Starred up grapples perfectly with the harsh themes, jumping from scenes that demand the most moving of performances from the lead actors, to the gritty insight into prison life, utilising the bleak cramped locations to their best.
With a rather suitably unresolved issue this film leaves you pondering the future that young offenders have to face dwindling away in the British judicial system an just how fair a conviction can be at such a young age.
