First third: cool.
Second third: incredibly tiring for the viewer, brilliant from a directing perspective.
Third third: cool.
Ending: magnificent.
Kyoto Animation deserves credit; in terms of the expressiveness of the characters, the imagery, the camera work, and the overall quality of the drawing and animation, it was great... The plot ranges from sleep-inducing to extremely interesting, charming, or emotional. The characters themselves are wonderful; each has their place and there's something to love about them.
Vinland Saga Season 2
It might not seem particularly noteworthy, but 20+ episodes were watched quite easily, so I'm giving it my seal of approval.
