This is a sombre version of the Arthurian legend, and in my view very much in tone with Thomas Malory's 15th century version. The latter is dark and foreboding, and so is this film. The deeds of arms of the knights are represented in terms that undermine the ideals of chivalry. There is only death, blood and severed body parts everywhere. The heap of bodies on which the last shot of the film focuses is the climax of this violence.
At the centre of this film stands the love between Guinevere and Lancelot, sublimely represented in the film: Guinevere waits for Lancelot's return in silence, and suffers for her love of him. Lancelot has come to the point where he tries to resist this love, for the sake of chivalry, but it is interesting to see the way in which he fails in his attempt to relinquish Guinevere.
I dare say this film is essential for anyone seriously interested in the Arthurian legend, and for anyone who has a clear understanding that the latter is not romance Hollywood style, but much darker. This is definitely not a film for everyone. There is a lot of blood and violence in the film, its atmosphere is dark, the dialogue is designedly monotonous, to match the sombre mood of the film, and there is no musical score throughout, except a very little in the beginning and end. It is exquisite in that it tells the story of a great love, accompanied by great suffering, and in that it demystifies any romantic notions we might have had about Arthur and his knights, as seen in other films of the genre. The austerity of the interiors also does away with our romantic illusions.
The acting is amazing, and I identified with the actor playing Guinevere in particular. The last scene of the movie, in which Lancelot, dying, says only one word: "Guinevre" (French version of Guinevere), stays with the viewer forever.
