Bobber owners beware: The Bobber is the object of direct scorn about 3/4 of the way through the film. Not entirely unexpected and not anything we haven't heard elsewhere before, so I just smiled through it.
Beyond that, the movie is mixed to me. The format is repetitive and gets a bit boring. It's really one talking head after another, even if often interesting talking heads that I like to hear from. It's almost entirely made up of interviews with custom builders and/or bike show organizers. To be fair, we are warned at the very beginning that "this is not a film about motorcycles, but about motorcycle people" or something like that. The problem is that hearing them talk makes me want to see the bikes more, and in more detail, which we rarely do. Plus, you tend to get six people in a row saying the same thing about the same topic, before moving on to another topic, in which six people say the same thing about it...
But of course the good part is that these are some of the most interesting builders out there, and it is nice to see and hear from some that I have followed a bit throughout their careers: Tony Prust of Analog, Jeremy Cupp in VA, the guys from Revival Cycles, Classified Moto, etc. These who appeal to me tend to be the more straightforward, bike oriented people. But there are also a few too many who try to wax poetical about motorcycles and the meaning of life, and as expected a tendency to look down on anyone who rides a factory bike.
So, to me worth watching, but not as good or compelling as it could have been.
