I mean it's alright, the battles were good and well done but the movie totally glossed over Napoleons rise to power and you don't really get much of an introduction of how he even became Emperor in the first place.
It fixates way too much on his relationship with Josephine and it just doesn't do a man like Napoleon justice.
The movie shows very little glory around him and just portrays him better as some generic military leader rather than a military genius.
