The midnight documentary at the Alamo was great. A filmmaker explores how the MPAA rates films and finds the whole process to be capricious and shrouded in secrecy. To find out more, he hires private investigators to track down the identities of the people on the ratings committee. There's lots of talking head footage of filmmakers talking about their struggles to get a NC-17 rating turned into an R, but it's cut well with the PI footage and there's a strong narrative flow. The Q&A afterward with director Kirby Dick was really insightful, with Aint-It-Cooler Harry Knowles confirming the MPAA's secrecy by talking about his own investigation into the ratings board that was dropped from his book due to legal concerns.
