I second that, Mushi Shi is great. Some other more serious/non-childish Anime I can recommend to Sp4 are Legend of the Galactic Heroes and Monster (they're quite long however). Both of these series are often compared to Death Note, but are not really that similar in my opinion. There really aren't any Anime like Death Note :(
