I feel that I have to start this review by saying that this is the first anime I've seen in a long while, and that lately I find most of them childish. While I can't say I felt that way about Death Note (for the most part, at least) I did found a lot of plot holes, some very unbelievable scenarios, and some characters acting way dumber than a normal person would (this probably to highlight the intelligence of the main characters, but it works poorly). Finally, I felt the series overextended, to the point when I was bored and wanted it to end. It would have worked better with around 20 chapters.

Again, it's not bad, it's not that childish, and it's overall interesting. But for the love of the god of movies, it doesn't deserve a 9.
