I have been discussing this with friends today after DS was incredibly angry that 2 young children talked loudly throughout the Avengers last night.
There is also a story in some of the papers today about a woman with Aspergers being 'dragged' out of the cinema for laughing loudly during The Good, The Bad and The Ugly.
On the one hand it seems discriminatory to restrict access to people with certain disabilities from the cinema, on the other the people who have paid should be able to enjoy the film.
WIBU the noisy person, even if it is beyond their control, or the intolerant person even if the noise is spoiling their viewing.
