I can tell you from my experience seeing all these tags that it put a lot of visual energy and animation into each train ride. A lot of people thought it was bad, but I saw a lot of young people who wanted some kind of recognition - any kind of recognition. I didn't do graffiti or tags, I worked in my studio, a tenement 5-floor walk up but it's what I wanted too. Someone to see something I did and acknowledge it. All the tags inside the trains created AN ALMOST ATMOSPHERIC MULTI-LAYERED HASH OVERLAY AT EACH SUBWAY RIDER'S HEAD. It was as if their thoughts came alive like in the comics. BLAM! SMASH! That's how I read the scene. A lot of people wanted it shut down, but I found a lot of energy just bursting from the seams in New York City at that time and the tags and artwork all over the trains was a great part of it.
