I have to disagree with those who feel that the engines being "cross" with each other is not something they want their children to watch. I too was not sure about the content until my son misbehaved and later apologized for being "cheeky" (a common term used in the DVDs). Although the engines are cross with each other, they always learn a lesson: it's not nice to tease, everyone makes mistakes, the engines are "grounded" when they misbehave, etc. My son loves to watch Thomas, and often acts out the stories with his own train set.
