I mean Netflix usually produces quality shows. Do you not have Netflix? Some of the best shows right now are on streaming services. Its won 20 emmys by now.
And personally i don’t really agree with the mindset that Japanese media have a unique approach to storytelling, honestly I think it just boils down to the writer.
But in terms of interfering with the original story, I can see some improvements that could be made, but it I can see some changes being made in order to appeal to American and European audiences. Though I’d say Umineko wouldn’t need that many changes since it kinda has the same appeal Baccano did. Like it feels more ‘western’ in a sense.
