What are some good metal related documentary films like Until The Light Takes Us?

I underserstand and agree with a lot of this, but you're making assumptions without knowing why or how this came to be.

Because it's a completely directionless hodgepodge collection of interviews with his pseudo intellectual analysis of metal culture where the only message he could possible make is the ridiculously shallow one that metalheads don't fit grandma's menacing stereotype of what a metalhead is. How fucking deep.

How is it directionless? It starts with a summary of who he is, he has a thesis, and then he goes from there. It starts with metal's influences, and goes onto explain the start, the fans, and how we are viewed in popular culture. Everything there is structured well, and it goes as deep as it can for the time that was allowed. And yes, the overlying message is about how we aren't what we're made out to be, and that's obvious for us, but that's how we're still viewed in the public eye. It is a deep message, and he hits many other subsections of the topic.

He also somehow tries to speak authoritatively about all of metal in general and of the whole metal culture, without even comprehending the breadth of the diversity in the culture and even in the music, not to mention he barely has a fucking grasp of death, black, and doom metal.

This isn't true. Extreme metal is actually his forte, and he played(plays?) in an extreme metal band. The reason he didn't go to in depth with harder sub genres of metal is because of VH1 Classic (Stupid, I know). This was also the reason he had to crowd-fund the Extreme metal episode of Metal Evolution (a better, more concentrated version, in my opinion).

We have evolved past listening to what Dee Snider thinks he knows about metal.

Did you watch the documentary? He interviewed Dee because Twisted Sister was one of the bands effected by the alligations of hard rock and metal music. He's important, and had something of value to say.

that individually may be kind of interesting to some fans, stories that you should probably already known,

The point of this was to appeal to both metal fans, and non-metal fans. He did a really good job at this.

And seriously why the fuck are you including Kittie, Korn, and Slipknot into a metal documentary... especially in fucking 2005?

Look, I hate nu-metal, but you can't deny nu-metal is a part of metal's history. He got the chance to interview them, and he did a good job at it. To ignore a whole sub genre, regardless of whether you like it or not.

I agree the documentary has serious issues, but as a whole; it does hit the core of metal, and it is very detailed, and is a good introduction to newcomers and fans alike. Everything I didn't respond to in your comment I agree with though.
