Best documentary films to watch?

I was recently watching some stuff on PBS—one program was about a local violin maker out in the Midwest, and another was this intense documentary about a remote island off the coast that was filmed right after the war. I’ve always had a soft spot for documentaries, especially those deep dives into history... there's just something about seeing how things used to be.

Do you guys have a favorite film you'd recommend? If you can find a link on YouTube, Google Video, or Vimeo, please share it so I can check it out...

...don't have any links handy, but I've been bingeing some documentaries on PBS lately... they really have a solid selection of the old classics... there was this one mixed bag—some vintage footage blended with newer stuff—about a massive storm surge hitting a major port city... also remember an awesome one about those old big car shows they used to hold out in the suburbs... just great... honestly, we need more of that old-school stuff...

Yeah, I'd definitely love to see stuff like that too—so if anyone happens to have anything saved on their computer, feel free to send it my way or, better yet, just upload it...

Hey, I stumbled upon this...
