I just saw Argo finally and actually liked it more than Lincoln and Django. I can't speak to the rest of nominees. It's a movie, they have to insert some creativity into it because rarely do real life events make for a good movie. If the whole movie built up to the group going through the airport at five in the morning with absolutely no problems whatsoever, I'm not sure you would have walked out happier about them sticking to the real life events.
I also wouldn't have had an issue with Django winning, but Lincoln was just brought down by Sally Field. I understand she was nominated for that role and I normally really like her, but the entire group I went with walked out of the movie pointing to her as the weak link and for me it put the movie a notch below the other two.
