This film is much more than a simple depiction of a criminal underworld. What it does very effectively (particularly George MacKay as Tim) is convey the emotions one might feel when in a position of weakness and faced with apparently insurmountable controlling forces, to be constantly "up against it", and the impact this has. The film is necessarily bleak, but is punctuated with occasional slightly more light-hearted moments, such as an affectionate exchange between Tim and his sister, and excitement such as the brilliantly filmed car chase. The shots of Tim, his girlfriend Lilly and their new-born baby towards the end of the film are hopeful and visually appealing. Overall I found this film engaging and insightful.
