I loved This Is It. Listening and watching him rehearse his songs was like being in a live concert. His professionalism and involvement were evident. We can clearly see why he was the King of Pop and the greatest entertainer the world has ever seen. I didn't notice two hours had passed when the film was coming to an end. As a MJ fan, I felt happy to see him happy, and sad when he sang the J5 medley, and pictures of him as a child were shown. He looked so energetic and lively, that's when it hit me he's no longer with us. This movie is definitely a must see.
