You cannot review this without comparing it to Truth or Dare, even Madonna said in a recent interview that the two go together.
This time round its the Re-Invention (2004) tour that is backdrop, where in Truth or Dare (TOD) it was the Blonde Ambition tour (1990). The Re-Invention tour was hyped at the time because of the heavy focus on the back catalogue used, and the fans loved it. The same method of filming is used in IGTTYAS, black and white over colour for live performances. The dancers again are used as characters but this is where the film goes off track slightly. In TOD you managed to really got to know who the dancers were, you became familiar with their faces and humour. Here you rarely get any of that, all the focus is on madonna and Guy Ritchie. There just is not a good balance between knowing madonna and what its like being on a world-wide tour with madonna, dancers and crew. Yes the prayers are all here again but the edits are all so quick around back-stage antics. It all passes in a blur and you have no idea what really is going on. The live sections are better as you get a better feeling what it all looks like when its up and running. I thought that the whole film did not flow properly because everyone either went on for too long (meeting her dad at the ranch) or too quick, that back stage scenes. Madonnas children add some delight to the show, you become aware of the effects on them of what its like having madonna be on a world tour.
So the film is a great show of madonna in her 30's to madonna in her 40's. its a great in-look on family life and how it works around madonnas life. Its just a shame the tour/film has not as many characters this time around.
