Do everyone else a favour and leave the kid at home. I realise it's a kids' film but if your kids can't behave don't take them out in public where they're likely to ruin the film for others.
There was one brat that spoke and cried through the whole film and the parents were quite happy to let the little fucker yammer on and on and the mother even kept moving between seats (one of them much closer to me) with the kid for some fucking reason. Got on my tits. They don't appreciate or understand what they're watching anyway.
