I like the very beginning when it’s more like a grumble. When he starts yelling my biggest problem is the pitch is much higher…
I thought so too. Going back, that first grumble (at least, what I think you’re talking about) is present in the English version as well.
I think the main problem with the new noise is that his mannerisms go along a bit more with ‘noo’. I feel that he should be shaking and convulsing a bit with the new Japanese audio, more visibly distraught.
