Could have been so much better. (**Spoilers**)
Hey filmmakers, when you didn't get the interview you wanted with Hughes, you should have rethought the structure of your film. The obvious choice would have been to open the film with the raid on Hughes' house and ensuing disappointment, then go back to the beginning and create a story from THAT. That would have given the film somewhere to go. As it stands, you have an hour of pointless dramatic build up that falls completely flat in the last 5 minutes. Then you just give up and roll credits. Too bad, because this could have been a really interesting, thoughtful documentary.
Also, the whole premise of the documentary, that Hughes' work was somehow an accurate reflection of any real teenager's life, is a complete misreading of the films. The reason everybody loves these movies is because they are romanticized wish fulfillment with a little bittersweet instant nostalgia built in.
You also fail to acknowledge other than peripherally that Hughes has writing credits on up to 2008. He didn't disappear, he just got tired of answering the "What was the inspiration for The Breakfast Club?" question for the 8,325th time.
After an hour and 13 minutes, I now know exactly nothing that I didn't already know about John Hughes and his films. What I got instead was a boring road trip and some throwaway dvd extra-style star interviews.
