For anyone complaining about the artstyle, try reading the manga (if you're into that). It's definitely easier on the eyes, whenever I see clips of the anime I get kinda freaked out by the character design (it feels like a pretty big difference). I hated the style at first, too, but I got used it.
As for the anime, I haven't really watched it, but I know it's definitely not my thing. Weekly anime based on huge manga like One Piece tend to stall, have fillers, etc. Also, it'd take a hell of a long time to get through. I prefer the short stuff.
Oh, and yeah, the end of Death Note was awful. I didn't necessarily mind the result, but the way it happened felt pretty forced. My personal ending for the manga would be right after the, erm, halfway mark.
