Again- nothing wrong with adults being entertained with children's movies or anything. I just think when they occupy more than 2 hours of your life, then you probably need something better to do with your time. Or at least spend it reading something memorable that relates to your life. What makes something a children's book? Well...simple- If it's targeted solely towards kids, the material is on an elementary reading level, and the situations are something that only relate to that age group, then it's a kid's book to me. You've gotta be a pretty simple individual to keep entertained by a Harry Potter book for longer than 2 hours.
