Biggest waste of 3 hours in a cinema. The movie isn't even worth watching if you had it for free on a streaming platform.
The movie lacks all the fundamentals that you'd expect from such a piece: a certain degree of historical accuracy, good narration and storytelling, decent dialogues. None of it.
It's basically a collection of key highlights from Napoleans life and jumps abruptly from one part to another, without any explanation, historical context or storytelling.
Save yourself the time.
