I only write this to say thanks to the positive reviews on this page. I was initially put off getting this as there were so many negative posts regarding this film. But a mate got it for me and I thought it was a quietly brilliant film that truly deserved more attention.
The plot loosely, is a gang from Bristol do vicious and sadistic so called 'happy slapping' and film it on their mobiles, they are a dysfunctional generally unlikeable lot held together by an invisible bond seemingly based on mutual violence and fear of the female `leader'.
The main character Cal, stops a French exchange student getting a kicking and is thus ousted from the gang. He then ends up having a relationship with Olivier, but his former gang mates will not let matters rest there. The reasons reveal themselves in a manner of ways and at a rate that does not undermine the main storyline. His best mate from the gang is particularly vicious about the 'betrayal' of turning out 'queer', but as Quentin Crisp once said 'some roughs are pretty queer and some queers are pretty rough'.
Some of the detractors are right in that some of the characters are overly stereo typical and there are more coincidences than a Dickens melodrama. Also suspend belief at someone gaining access to a computer quicker than a super hero. However, this is a shoe string budget effort which is watchable, well acted and actually moving in parts. And it is an indie British flick not based in London and should be lauded for that if nothing else. The sex scenes have been called soft porn by some reviewers but they just felt natural given the content and circumstances in which they take place. If you are wavering about whether to get/see this or not I urge you to give 'Shank' a go and hopefully like me you will find it very much worth the effort.
