Whether one is a football fan, or not the behaviour portrayed in this documentary should shock you, it should make you ashamed to be English, it should make you ashamed to be a football fan. Instead by totally ignoring the consequences, by not asking the people interviewed pertinent questions regarding their behaviour what this doc ends up doing is normalising violent horrible behaviour.
See it is OK to drink too much and riot as long as football is involved, there is no morality just ignorance. This documentary confirms what many of us know already, that football is followed by a lot of ignorant men driven by the fear the will ose the respect of their peers if the don't behave like they do in this documentary.
View it as a warning.
