M.S.
I have not seen "This Is It", but I wanted to let you know about a website called commonsensemedia.com. It reviews movies, tv shows and video games. People who have seen it let you know how it was and if appropriate. It's also rated by the kids! The exact words/situations in the movie are displayed. For example, I went there for the movie "RV". It mentioned the words used in the move. I, personally, didn't think "terd" was all that bad, so I let my kids watch it. Other movies I have checked up on, I've decided they were not for my family. It's a great resource!
