I don't really understand the main criticisms:
1. "Historical Inaccurate." There were a few scenes that were historically inaccurate. Napoleon wasn't at the beheading of Marie Antoinette. Napoleon didn't fire at the Pyramids. A few battles were longer and harder than the movie depicted. The water at Austerlitz wasn't that deep.
Cinema is different than history. Gladiator is mostly fiction. Braveheart is half fiction. Napoleon is like 5% fiction. I don't really understand the argument here. When you condense a lifespan into 2.5 hrs, you're going to have to embellish events and gloss over others.
2. "Napoleon was awkward." That is true; he was not a people person. He inspired through his leadership in battle and tactics, but he wasn't actually that close with many people. He supposedly got along with children and animals, and Josephine. This explains why his battle tactics were so excellent, but his diplomacy was so bad. A lot of tyrants in history share this personality.
3. "What was Scott and the writer trying to say?" Many people, both left and right, were confused by portrayal. Was it anti-war, anti-french, anti-ambition? I think he was trying to say exactly above. Napoleon was good at conquering things, and bad at diplomacy, stubborn and egotistical, and that leads ultimately to his defeat and a lot of human suffering. Josephine somewhat kept him more rational, but that fell off and perhaps made his judgements worse in battle.
4. "There was too much Josephine." No, absolutely not. He was madly in love with her in real life. It dictated much of his life.
I enjoyed it overall. If anything it demonstrates the shortcomings of film itself. I recently rewatched the shining after reading the novel and was surprised at how condensed it was. From 1920s to 2000s, we were accustomed to this shortcoming, thinking it was impossible to do otherwise with such a low TV budget. Now, films like Napoleon feel exceptionally short compared to novel-like high-budget TV series. I personally think Napoleon should've been a multi-season series. Why can't the theaters screen the series? I would definitely go to see something like Shogun releasing soon.
