3.5, so maybe I should give an extra star. I was wnated more of the city planning/social justice thread that ran through, really enjoyed his use of space (and the map), and how he connected these to film, although my appreciation was hampered by lack of knowledge about the films referenced. I was frustrated/annoyed with the introduction of the prisoner of war massacre by the Hitlerjungen. Suspect I was missing something, but found that final chapter really frustrating as a result.
