About as satisfying as Napoleon's frantic thrusting I'm not a history buff, so my slightly negative review has nothing to do with, as others have pointed out, the historical inaccuracy of the film. My issue is that for a film with such a dramatic theme, it really didn't manage to create much of an atmosphere. I think this is largely because the film tried to fit a lot into 2.5 hours, meaning the non-battle scenes were short and lacked depth. In addition, the scenes themselves were poorly arranged and lacked continuity with one another, this further diminished the film's ability to build any mood. There was very little character development, and all the characters barring Napoleon and Josephine were somewhat peripheral or transient. Napoleon was also portrayed as a bit of an immature buffoon, at times his dialogue actually felt a bit Monty Pythonesque. That being said, the battle scenes and cinematography were epic, saving the film from being completely unenjoyable.
Worth a watch, but for a film with this budget, by this director, and with this cast, I'd expect A LOT more.
