The quality of animation in those two Anime is high but fairly common, though more so in movies than in series. The quality of animation in BES is very rare, and very cinematic, and I can’t recall anything in recent years that looks anything like it.
What are you talking about. The show is a boiler plate revenge type history in comparison with original fantasy anime exploring what it means to be human and a period crime drama with a compelling female lead pinging off an interesting supporting cast. BES is fast food.
Neither of those series were nominated for this award. I imagine they weren't due to not meeting eligibility requirements (release dates, platforms, spoken languages... dunno).
