This documentary on subway grafitti in New York City in the early 1980s had it all: it was beautifully shot, had a great soundtrack, and captured the essence of what was going on in the city after the 70s and under the regime of Mayor Kotch. The best thing about this documentary is how it can be studied on so many levels- it makes you realize why "bombing" is done and what it accomplishes. It helps you understand the psychological reasoning behind it, and how it plays on human character traits such as territorial rights, pursuit and the need for recognition. It shows how graffitti had a strong impact on society, and how it tore some homes apart.
