I was very optimistic about this anime to begin with. The premise is interesting, but once I got past the 4th episode I could see that the plot was going in a direction that was ultimately leading nowhere. I watch until episode 8, but I really just couldn't ever get myself in the mood to watch it again after that. The shame is, I really liked the characters. And a warning for anyone who plans on watching it...I've seen spoilers...and the anime series ends without anything being resolved. If Spiral interests you, perhaps you should read the manga rather than watch the anime?
This is really just an amazing anime. For those who have read the manga, the anime follows the plot line completely, the only difference being in the very ending scene. Death Note contains the complex, interesting characters of Light Yagami and "L", and a plot that leaves you wondering whose side you're on. Overall, this is simply fantastic--a masterpiece.
This is just a really cute anime. When I first began watching it, I wondered what kind of ridiculous crap I had gotten myself into, but really, it's hysterically funny. There is no dramatic plot or villian, just an interesting situation and a lot of awkward moments. The animation isn't wonderful, and Karin (aka Chibi Vampire) is not a thrill ride, but it is definitely worth watching.
