the rules state that a child under 12 can go IF accompanied by an adult who judges that the film is suitable for them hence allowing parents to make their OWN judgement about what their OWN child can cope with! shock horror parents making a judgement about their own child!
my kids sit quietly through films and dont pester adults or moan about not being able to see (they provide booster cushions in our local cinema so kids can see if there are adults or taller people sat in front of them) if they didnt behave we would take them out, but the cinema is an occasional treat and we have never had to take them out yet, they know how to behave!
my kids also watch ben and holly, dora, garfield etc, but they see the occasionial film, they like chitty chitty bang bang, and one of our dinosaurs is missing, lots of classic films as well but the boys love transformers and as for conditioning them to violence, they are robots, its make believe in the same way that they sometimes play with toy lightsabers or water pistols or guns made out of lego, its imaginative!! they are well aware of the difference between what is real and what isnt!
like i said language wise they will hear the same if not worse in the school playground, esp ds1 who is at high school! yet he is 11 and technically not 12 so should he not see it? laughable!
they dont play violent videogames, i wouldnt let them watch scary/horror type films, but this is a film about robots!!!! its not real, its based on a kids toy and tv show (origionally) so of course children are going to see it!
