Over where? Britain?
Yeah, I'm assuming Blighty because I'd agree that it was quite well maintined over here - it's actually not strictly abided by, but most parents would use it as a general guide, like taking 2 years off the recommended limit for example, as most british 16 year olds have commited more attrocities than they'd ever see in a movie!.
Really, it should be a (sensible) parents decision whether or not a movie is suitible for their kid. If your kid is more sensitive to violence then it's upto the parent to put in measures preventing them from seeing anything they shouldn't. Heck, when I was about 9 or 10 my uncle let me watch Nightmare on Elm Street, to be honest I remember being more scared at Doctor Who (damn you Davros you freak!) than the adorable Freddy.
