Am I being unreasonable in thinking parents shouldn't take toddlers to the cinema (parent and baby screamings -- sorry screenings, apart) unless they are able to sit through it; without shrieking, needing the plot explained to them all the way through at normal volume, or wandering around disturbing other people?
I think it's selfish and can spoil outings for other families.
Even U rated films are only rated suitable for children aged 4 and over.
