Many reviews are critical of this movie: i agree.
Saw it today and walked out not sure what to think. Whilst not fully knowing all the history depicted in this film, it seemed to cover the highlights. But it tries too hard to do too much. Sure the film pivots around the central figures, but doesn't do it justice. It may have been better not to do too much. It was ambitious to do a movie on Napoleon. Each sub plot and battle could have been a movie in its own right.
Whilst I only gave it 2 stars I will still recommend the film due to its cinematography, some scenes are just spectacular, if not brutal, to watch.
Just a note that it is a very long film without a break.
My experience was also spoiled by an older couple next to me who had a need to make constant comments to each other. Rude.
