The most brilliant thing about the documentary is in the end when they finally realized they didn't win the White Hosue. The gradation of pain and disappointed hopes in their faces is classic.
It was like a good schedenfreude moment of hot chocolate fudge bowl of ice cream. I spent the entire 40 minutes during the documentary thinking this man was perfect in every way. (I hate perfect people by the way lol) The minute he finally lost his dream, the moment he gets sad and asks his people to talk to the secret service people to stop their services. (really sad moment, he kicks the secret service out before they kick him out. how sweet lol) He said they will just drive me home and that's it. 'They need to go away. Its makes me feel ridiculous.' That was a laugh out moment! Finally- I realized-he is not perfect after all! (I also realized a whole lot of people and a whole lot of things about Mitt but I cant share them here lol ) So, in the end, he did come off likeable and normal just like us.
