One of my favourite Anime of all times!
The artwork is good, the anatomony is really good. The characters has good body physiques: not too fat or too skinny. Plus, the shinigami are good too in physiques. Inhumanly tall with extremely long limbs, or tiny.
The plotline is good too. Psychological too, and its hard to figure out who's the next step fastest than the other. The protagonist has turned into an antagonist. A girl is devoted to her feelings rather than killing, and she would die for the one that she loves. Besides that, I think the action is good too.
The series is awesome, plus the characters are good to love or admire too. L is my personal favorite, but I won't talk about that.
Light's goal to change the world is good, but his goal has been too extremed and he became too obsessed. That was his weakpoint, plus his perfection.
A great series to watch and read, but the ending is bad. It was sad for me to see it end like that.
That's all I can say.
