The interviews with Maple, Dr. Daks, and Ichabod are great, and reminiscent of some of the classic graffiti documentaries. They give insightful looks into the culture that remind you why graffiti is cool. Definitely where this doc shines the hardest.
Other parts of the doc can feel like an anti-graffiti PSA. Theres a lot of runtime dedicated to explaining that trains are big and dangerous. There are some tragic examples, but it feels tedious.
There's also a lot of time showcasing the relationship/life struggles of older-generation writers. Sad and real stuff, but most people aren't putting on a graff doc to hear about someones divorce. Conveying that being obsessed with trains isnt a turn-on doesn't really require 30 minutes of screentime.
The beef segment is cringe beyond belief. Guess the doc needed some drama but talking about beating people up in a freight yard in front of your kids isn't a good look.
There are several aspects of freight graffiti that are left out, and that would have been great in place of some of the other segments. Most obviously is that younger writers are almost entirely omitted, and in a documentary about a historically youth-driven culture, this feels like a missed opportunity. Interviews with younger writers to supplement the parts with the og's would have made this a more complete picture of freight graffiti, and given some fresh insight that hasn't already been well documented.
Overall, its worth a watch, but might not deserve a spot on the shelf with the classics.
