I don't really see what the hype's all about.
The beginning hooked me in but I started losing interest after Raito lost his memories. Then I got bored after L died. Haven't read it since though I'll probably catch up with during Christmas break.
While it's a good series, I don't think it's that good. I'm reading the manga, and seriously... The series is good, but not that much. Most of the play and counterplay by L and Raito is burnt-out and obvious (that is, if you have seen enough detective shows before,) and Raito is an a*****e with a god complex the size of Russia. Or as L so skillfully said, he's an "immature sore loser."
I'm in "Page 80" right now, and I only keep on reading to see when and how Raito will kick the bucket. The premise and the whole "kill people by writing their names in a book" lost its attractive by page 30 or so.
I don't usually read manga, but in this case it's easier to check manga scans than waiting three or four hours for each episode to download (darn slow connection...)
I'd give the manga a 6/10, and I've heard the show's much the same thing (and a 6 is good, only show/manga that's got a 10/10 from me is... Wait, none did.)
Maybe if they chopped down the whole "OMG uber-smart dudes pissing contest to see who outsmarts each other" bits, the whole manga would be much more entertaining, but as is, it's something I won't re-read (or bother with downloading the anime) after I'm done.
