In sixth grade, we all had to write this opinion paper. Most wrote about things like why we should be able to chew gum in class - I wrote about why women should receive equal pay.
There were definitely bands and musicians I liked that drove my mother insane. I probably liked them all the more for it! Bjork drove my mom nuts. What I listened to was actually pretty mom-friendly for the most part. I wasn't very rebellious.
The nice thing about a documentary, I think, is that so much of it is editing, too. You sort of get to keep making decisions. It's not as much like when you do a narrative, fictional piece, and you have a certain number of shooting days, and you're like, "Well, that's what it is." You can continue to seek out more photographs or try to find more footage. The genre gives you the ability to keep working on it, which is great for a first-time director.
