I welcome this new writing collaboration between Ben Affleck and Matt Damon. With a fantastic cast, very well acted and with realistic sets, it tells the story of the last "legal duel" in France, or a fight to the death between two men to settle a legal dispute, in this case the rape of a wife, leading to damage of property. Composed in the style of Rashomon, it shows the same sordid story from three different points of view, neither of them proclaimed as truth (except by a very cowardly fade out in the case of the third act). It is difficult not to enjoy the film with such talented people working for it, but unfortunately the structure and the length of the film make it feel a little slow. I mean, yeah, it's the middle ages, slow was the default value, but still.
This is based on a book, so the scenes and the story are pretty accurate. When people start complaining about this and that, you just have to ask them if it's like in the book, researched and written in years by a university professor of Medieval English literature. It's about how women were property, men were crazy and everybody was living in drafty dirty places and fought wars for no good reason all the time. Basically feudalism was bad. Yet one has to wonder, if they had the same story told about three times, how much of the book was preserved and how much of Eric Jager's effort was lost? Perhaps, if you are passionate about the subject of feminine rights in the 14th century you should get reading instead of watching the film.
Bottom line: very well done, but none of it is meant to be entertaining. There is no fun, little action, limited character interaction. Great acting fills a bit of the void, and the subject is kind of engaging, but after two hours and a half of this you're just glad it's over.
