Children love the Diary of a Wimpy Kid series. The half drawn, half written books center around a middle school student named Gregg Heffley and his adventures dealing with friends, school, and family. There are currently eight books in the series as well as a special movie diary book.
The first four books have been adapted into three films, Diary of a Wimpy Kid (2010), Diary of a Wimpy Kid: Rodrick Rules (2011), and Diary of a Wimpy Kid: Dog Days (2012). The plot from the third book, Last Straw, was split between the last two films. The films seem to generally fly under the radar a bit, but like the books they are silly fun for kids.
