When this video came out I was surprised at the amount of negative reaction from film photographers. I think that you've got to put it in perspective: It's some guys who run a film lab, going on a road trip and talking to people (probably their clients) about why THEY shoot film. Most of all it's just fun.
We all have our own reasons for shooting film or digital or whatever... Best not to get too worked up about why other people do it. Just be glad that they do.
That being said, if you watch another recent doc, Everybody Street, you'll hear some of the most famous New York photographers saying the same kinds of things about why they prefer film.
