Despite what some may say, this is as great as adaptation of the manga as one could ask for. The actors portray their characters perfectly. The calm menace of Light is portrayed perfectly, with a clear distinction between Light and "Kira" Light, which is impressive considering anime would allow stronger visual cues. L is an honest to god incarnation of his manga and anime counter part down to the smallest detail. Ryuk is also impressive, the CGI effects do him justice and his voice is much better then the one for the subbed anime which was horrendous.
Now obviously the plot needed to be condensed and changed but they did very well. All the important parts are there and the ending, which strays far from the manga, is actually even better then what actually happened in that instance in the story. It wasn't conveyed the complex story involving a genius highschool student who's use of a notebook that kills people that get's him involved in a proverbial chess match with the detective L, but they did a fine job. Misa, despite her short screen time, acted the part of Misa perfectly, down to the voice.
Fans of the manga should enjoy as long as they don't expect an exact replica of the manga, and fans of thrillers should enjoy this as well.
9.5/10
