The hot movies of 2013 seemed to be docudramas like The Wolf of Wall Street, American Hustle, Lone Survivor, and 12 Years a Slave. All of these were based loosely on historical facts, but ruined by fictionalizing crucial parts of the stories. The slave movie got the best picture oscar even tho the voters did not necessarily watch it. Apparently they felt obligated to endorse the anti-racism message.
It appears that the public is attracted to a movie "based on a true story", but then the movie makers just rewrite the story to suit their artistic preferences. I think that all of these movies would have been better if they stuck to the facts. I would rather see a purely fictional story, than a gross misrepresentation of the truth.
Other big winners were Gravity and Her. The chief appeal of Grevity was supposed to be its visual realism. It gave the appearance of scientific accuracy, but it had numerous misrepresentations. The main purpose of the movie seemed to be to mock the idea of using female astronauts, as the one in the movie was a bumbling incompetent from beginning to end.
I previously argued that Her is boring. The only thing of interest was the artificial intelligence, but much better AI is in movies made decades ago.
