The Last Duel got some strong points - acting is good and the production fine. What drags the movie down for me is the duration and somehow I was never really engaged with the main body of the story (the crime), so I had from time to time really to fight to keep my attention on the movie - to use Akira Kurosawa's different perspective technique (Rashomon) was in my opinion no wise choice. What's left to say? Best parts of the movie are for certain the battle scenes and the duel in the end, and the high production value regarding settings, costumes etc. The Last Duel - for sure no bad movie but belongs certainly not to the best of Ridley Scott's work.
