"A mental hospital is not the place to hook up," observes suicidal teen Craig Gilner (Gilchrist) during his brief stay in the psychiatric ward of a Manhattan clinic.
However, it proves to be just the place...when he finds himself drawn to fellow patient Noelle (Roberts), an elfin beauty with a propensity to self-harm.
Craig's wound up in the Argenon Hospital because - faced with a tough test to get into a posh school and unrequited yearning for his best friend's girl - he's feeling suicidal. Or feels like he's feeling suicidal.
Pitching up at the clinic, he finds himself admitted by a psychiatrist and it's only then that he realises he's actually in a secure ward. What's worse, his parents think he needs straightening out and a five-day stay will restore his mental health.
He's in good if slightly disturbed company. There's Zack Galifianakis' amiable (sometimes) bi-polar depressive, his Egyptian room-mate (who's never left the room) and a damaged Hassidic acid head who's dropped one too many pills.
And there's Noelle. A wrist-scarred waif who enjoys cryptic word games and is attracted to Craig after a random act of kindness to a fellow patient.
Based on the novel by Ned Vizzini, this is a charming tale - think a feelgood One Flew Over The Cuckoo's Nest - which is considerably boosted by Gilchrist's teen - a likeable dreamer who quickly realises that he's already got it made.
Occasionally steering just the right side of mawkish, it's an improvement on Ryan Fleck and Anna Boden's last outing - Sugar - and displays their inspired handling of ensemble casts.
You'd be mad to miss it.
