In writing this review I agonized how to start it; but here goes: Just because there is a clown-like character does not mean The Dark Knight is a movie for children particularly those that barely walk.
I began that way because I was distracted – fortunately not so much – by a child, who seems to me, not old enough to walk. The mother had enough sense to go out with the child before making too much of a scene. So before bringing your child for this movie watch Batman Begins and maybe this time understand it, or, keep note of the fact that Adam West is 80 years old. The Dark Knight is not for children!
