I think we've digressed slightly from the original point made.
True - apols.
Parents like that are either irresponsible or - once they see what the film is like - negligent not to take the child from the cinema.
My biggest bugbear with cinema these days is the incessant chat and the rustling of sweet wrappers. People seem to assume they are at home and can just behave like its TV in their living room - Sadly a wider issue - just manifest in cinemas.
I don't like going any more and try to go at odd times to avoid the whispering/rustling masses.
