Yes, this is one of the finest action episodes of Samurai Jack. The utter style and class with which the storyline is executed and animated is breathtaking, and the action sequences are lightning fast with arrows being more unlimited than Aku's evil.
Though the army that was decimeted at the beginning by the three blind archers without breaking a sweat was a robot army, it was nonethless a very chilly image to see their 'bodies' rotting/rusting in the snow, as they could just as well be human. As violent as Samurai Jack episodes can be, they contain no blood, as all Jacks adversaries which he cuts open are robots or machines. This only adds depth to the series, as it is obvious that the produres do not trade content for shock and gore value that would inevitably happen if blood and guts were splashing everywhere.
The archers are emotionless, lethally skilled and precise, and totally silent.
Jack must fight at an equal level to them to stand any chance of beating them. The sequence of the silent and black images, with splashes of beautiful sound and colour, as Jack make his peace with the world of pure sound, is utterly beautiful.
Then the attack and subduence of the three blind archers, their freedom, and the sheer evil of the well. I have never seen Jacks face in such a mixture of exasperated anger, despair and disappointment as when the true nature of the well is revealed.
A truly excellent episode.
