If ever there was a film with its heart in the right place, deviating not so much as a millimetre in any direction, it's this earnestly acted piece from director Gillies MacKinnon about a 10-year-old boy who has to look after his pathetically drug-addicted mother in a tough east London council estate.

It's got a talented cast, each doing an impeccably honest job, but this is a strictly thespian version of reality we're witnessing.

Molly Parker is smackhead Mel, whose fiercely protective son Paul (Harry Eden) doesn't know how to look after her; David Wenham is her dealer-boyfriend. An honourable and decently intended film - but every line feels like written dialogue, particularly Paul's speeches about his mum.
