Oooh, like kids don't get crude jokes and curses from ANYWHERE else. ;-)
I took my kids (6 and 10 years old). They liked it although I doubt my six year old got half the jokes. My ten year old got maybe two-thirds of them. I don't remember cringing at any point thinking, "Oh no! I'm corrupting my kids!" Perhaps it was because I was too busy enjoying the movie myself. But you're right, it was NOT a "Disney" movie with complete wholesomeness. I think Dreamworks did a great job balancing kid/adult entertainment in this one.
