The curse of the 12 certificate

In the UK the 12 certificate seems to make every 10 year in the country want to put on some make-up, high heels and go on watch a film in the hope of hearing a swear word or catching a flash of nudity.
The problem with this is that I always seem to end up in a cinema full of bored, loud obnoxious kids watching films with an adult theme, in this case recovering from loss and surgery. Hardly thrilling for the average kid but quite moving and thoughtful for adults.
This is not the only movie that this has happened during.
As Good as it gets
Bed of Roses
The Village
Circle of Friends
Jerry Maguire
Sleepless in Seattle
Wimbledon
Notting Hill
Million Dollar Baby

Feel free to add to my ever expanding list or if you are a 10 year old who's managed to get into a 12 or 15 film only to be bored to tears add titles which you have ruined for us oldies!
