I finally watched the first episode with my friend (to clarify, I was seeing it for the second time), and they were complaining "where's the something extra in the scene with the Beholder? Where's his smile?!" So... as a favor to them, I'm posting an excerpt from the relevant manga chapter.
I get why the anime decided to rush the pacing to get through everything—and it mostly worked OK, but this scene is really one that deserves to linger a little bit more.
First of all, Fushi thinking of the nameless boy is always something that hits pretty hard, and they cut that out entirely. Secondly, in between when Fushi screams in joy (a moment where they're so genuinely ecstatic that they the only way they can express it by screaming is really impactful) and when the Beholder shows up, they should have had some time to calm down a bit. Otherwise, it kind seems too sudden to go from "YEEEAAAAAAAAHH!!!!" to "oh shit, my rope."
And by the way, how the manga juxtaposes Fushi's declaration of their freedom with the rope's very existence? Excellent. In general, this was a really big scene in the manga because it's the first time the Beholder has done something like this. He's literally and metaphorically releasing Fushi from the burden they've had to carry for five hundred years! It's a big moment. It needs room to breathe.
Also, because my friend will kill me if I don't bring it up again, the Beholder's final expression in the manga carries a certain kind of nuance. It's different from his usual stoicism, almost like a smile...
I still think the anime is doing a pretty good job so far (I'm enjoying it, at least), but I hope this is some good supplementary material.
