Winning awards and nominations at Cannes, Sweet Sixteen continues director Ken Loach's devotion to social awareness. After using film that directly affected legislative reform (Cathy Come Home) in 1965, his work has spanned the globe and a wide variety of social ills and with very varying fortunes in marketability. Sweet Sixteen looks at adolescent delinquency and the difficulties faced by youths who try desperately to escape the downward spiral that ruins their lives forever. The script, in broad Scots dialect, has an urgency and reality to it. The young actors come mostly from the deprived areas of Western Scotland where the film is set, many of them first-timers and of an age where they would not legally be admitted to the film. The scriptwriter bitterly attacked the BBFC over its ‘18' certificate decision, which was based mostly on the aggressive use of strong language. Meanwhile, English distributors looked at the use of subtitles to help adults south of the border cope.

The story follows 15-year old Liam (played by 17-yr old football player Martin Compston) as a youth who is determined to have a normal family life once his mother gets out of prison. The drug-dealing boyfriend of his mother and his empty-headed companion ‘Pinball', do little to make his quest easier. He opts for ‘means to an end' – a simple enough mistake we feel for a young boy in his circumstances. The consequences, of course, are told with shocking realism. Will the film have the sort of impact that ‘Cathy Come Home' had on homeless laws, and mean more attention is given to real support for youths in disadvantaged areas, rather than simply throwing money at the unwinnable war against drug dealing? The long list of agencies thanked in the closing credits shows how the people in the know pin their hopes on Loach – one of Britain's finest and conscience-filled directors – and one of our most ignored.

As someone who comes from Greenock originally, my first draw to this movie was curiosity. Having said that, I fell completely for the story of Liam. His character, played by Martin Compston, could be one of many lads that I grew up with. The need to be 'one of the big boys' an all prevalent force in this deprived, former shipbuilding town; even if that need is self destructive. The performances are stellar throughout, only the mother's character is weak. I am unsure if this is deliberate, or bad acting. Perhaps the film could have explored the lack of employment and the sectarian divide more, however it does tackle the drugs issue very well indeed. The other thing that may put people off is the language. There is nothing unusual about the frequency or the strength of it for Grenockians. But it is more usual for a filmmaker to give an essence rather than soak the audience in every single word.

Ken Loach makes films of political power and emotional intensity. If he has a flaw as a film-maker, it is that the overall body of his work is insufficiently varied, and that the same basic narrative (of essentially decent people fighting and ultimately failing to overcome their disadvantages) re-appears in a different setting in each successive film. 'Sweet Sixteen' is, however, one of his better works, in part because he resists the temptation (as sometimes he does not) to place a hero with a heart of gold at it's centre. What we have instead is a horrifyingly believable story of an ordinary kid getting into bigger and bigger trouble. Every detail convinces, and the quality of performances Loach entices from his inexperienced cast is of the highest order: the film is also a sobering reminder of the underside of life in Blair's Britain. Loach has a rare talent: it's on display here, but don't expect any surprises.
