The main crit I have for them is the scriptwriter uses too many words -_-
They make ryuk talk so fasssssssst owo Which is unlike him. Like for a simple line she made him say 'I did it because I was bored' and half through that you could barely understand him o-o a simple 'because I was bored' would have worked, and would have fit his mouth movements o_o
I think they changed the voice actors from what they were in the trailer; Light sounds oddly different.... Not bad, though
I really wonder what they'll end up doing in the second season, since the opening theme saz bad wurdz :B
