I saw this documental three times. I also played it in my user centered design class. It's great material for educative purposes, but for first or second semester design students, and particularly the design process at Smart Design and IDEO. I do personally empatize with the way design is done at those two firms. Dieter Rams interview is great. Although it shows the state of affairs and different points of view, it's scope is too narrow, mostly focusing in well known designers, curators, critics and studios from the US, Europe and only one from Asia (N. Fukasawa) Design book publishers (Phaidon) started to realize that there is a lot of good design activity beyond the U.S. , Europe and Japan. I't would be great to see a second part showing the work of Filipino, Brazilian, Kenian or Mexican designers or small design consultancies in emerging countries who have to apply a lot of creativity, obtaining great designs in cultures with less corporation oriented design philosopies, and more technology limited environments. I do agree partially with "JW's" review, Most of this people are involved with a small fraction of the produced goods in the world but it does generally sample the way many design professionals do their work.
Overall its a good introductory film, but I hope more deep filmed material on I.D. will show up in the future.
