Brotherhood has an age rating of 15 meaning it is unsuitable for under 15s. I believe the film has been given this age rating due to the massive amount of violence and sexual content within the film, as the legal age to have sex is 16, if the film was any lower it could cause problems around the UK such as an increase in underage sex cases. Also due to the fact that the film encourages a mass amount of violence it has a massive influence on teenagers especially since it features icons such as UK rapper Stormzy, people look up to him so may follow in the gang violence he incorporates in the film.
