All fans knew Michael Jackson could entertain and from seeing this film nothing had changed. What this documentary does give a bit more insight into though is his creative process and how well he knew his stuff. From his conversations with his musical directors and others there is now no doubt that he did have a lot of musical input with his albums/videos after seeing this film. I notice another reviewer mentions that he thought that when MJ was talking to his team that he thought he was treated like a delicate child, and maybe I did get that a bit. But more so I felt it was a professional who wanted everything to be perfect. If something wasn't right during a concert it would have reflected on him and as with everything MJ did with his music he wanted it to be as great as possible. Other than that and the direction and critiquing he does with the music, the clips that would have been played before and during a song during the concerts were great and looked pricey. We also see some brief interviews with the dancers that mention what MJ has meant to them and their careers. Lastly, some of the slight musical changes to songs like extra horns added to 'Jam' gave the song another dimension and were great as were all the songs with the cinema surround sound. Other than those things there isn't a huge amount to take out of this film if you have seen any of his concerts. However, you do see him a bit more intimately than his old concert videos and there ain't a doubt that these FIFTY! concerts would have been great and no doubt reignited his career. Obviously, if you love his music and are interested in what the concerts would have been like then this is worth seeing.
