I found this documentary on little Marla Olmstead to be very interesting. Documentaries live and die by the story they tell. If the story isn't as entertaining as fiction, you are going to be bored, and watching the doc. will be like a chore. That's what makes My Kid Could Paint That a diamond in the rough. It displays a child's rise to fame, an expose' on her work, and how her family deals with the fame that they may or may not have antagonized. If you have a solid decision on what side you're taking in the beginning, you'll seriously doubt your feelings by the end of the movie. I don't think the filmmaker goes to far, he mostly just records whatever he sees, and lets the story write itself. The parents on the other hand... that's up to you to decide.
