I can't judge different aspects, but as I haven't read the manga this ending was incredibly unique to me. After watching about 100 episodes of struggles and hardships and finally seeing how Shinta grows old and lives his last days, especially the touchy moment where he dies, brought tears to my eyes. Although first 60 minutes were kinda annoying, the ending was superb. The drawing and sound suited perfectly. Solid 8.5/10, but 5 stars for the anime itself.
