I really like him as Ghost. He sounds half robot, half mysterious space helper. Something not human trying to communicate like one. Which is exactly what he is.
When people talk about not liking his performance I totally respect that, but I don't understand. It's like a mix between C3PO and R2D2, feels dead on to what someone intended.
That said, the storytelling, script, and chemistry between voice actors is remarkably improved. Really glad to see them making such an effort.
Yeah I've never understood the complaints. He is playing an AI, not Tyrion Lannister. WTF did people expect him to sound like?
