Shame on you Metro

Took my 12 year old son to watch Night at the Museum 3 at Grand West for a 12 noon show, last month. During the screening a trailer was shown for Kingsmen - Secret Service. Son very excited about the story-line - youngster taken off the streets to be trained as a James Bond type agent. Couldn't wait for launch so him and his dad could go see it, because according to him a movie made for him and his dad. Watched the papers avidly to monitor launch and low an behold movie launched last week with an age restriction of 16. Not on New Metro! Why is an adult movie being marketed to youngsters during children's movie matinee performance??
