This movie has a a lot of problems, that being said, I didn't hate it. Granted I've never seen the anime. I was intrigued by the opening and stayed entertained despite the obvious problems.
William Dafoe as Ryuk is awesome. He has the perfect voice for this character. Granted The CGI on him doesn't look that good, and he has very limited screen time. I wanted more of him and his backstory.
Instead it sort of becomes a generic teen…
