One of the best anime i have ever seen.I"ll try to keep this short so no one gets bored.
Story:Death note dropped on earth by a shinigami with the ability to kill a person if someone writes his name in it while having his face in mind.Extremely plot along with fierce battle of wits make this anime exceptional.
Animation:Very nice animation along with the dark enviroment fit to the plot of this anime.
Sound:Just one word can describe this,Epic.From the OP song to the ending song and everything in between you will be just stunned.
Characters:Most powerfull characters in means of wits and the ability to adapt in situations in which a normal person would just fail .There is no secondary character in this anime ,the all have "a role to fullfill".
Overall:9.5/10 Must watch.0.5 point out because i lost some interest in the plot line when L died.
