Big disappointment. Other than a few battle scenes, the movie primarily focuses on Napolean and Josephine. There is no mention of Napoleon's war and battle tactics, his contributions to society through reforms and religion, and very little of his conquests. He is portrayed as a weak man and a fool. You would never know he was regarded as one of the greatest war commanders and strategists.
In addition, Joaquin Phoenix gives, what I consider, his worst performance ever. It appeared that he was portraying Napolean in a comedy that is set in the 1980's.
Overall, a very disappointing effort from a great director and leading actor.
