Just taken DD (age 11) to cinema to see High School Musical 3. Could not believe the amount of toddlers in there! I mean this a movie about a High School (quite shocking really as there was snogging and knicker flashing, pretty tame to what goes on in real high schools )so what relevance to a tiddler??
A couple of the little darlings were running round the cinema obviously bored because they could not follow the film(and I do mean right round the cinema not just in the aisles) while their parents just sat there and did not do anything), so along with the rest of them crying, wailing and screaming, it was difficult to hear at some points.
IMO from the age of 5, kids can sit quietly and watch a film and under that age, they should be denied entry!!
