Ouran wasn't bad (though I wish they hadn't messed with the opening song, it was so much better in the original). I've heard a little of Death Note, but what I heard was pretty decent. I've only ever seen Fruits Basket in the English dub and the only voices I really object to are Yuki's and Ayame's. Other than that? Can't think of anything.

I was curious about the dub once. I managed to make it to the point where Sai started speaking and then had to turn it off to prevent my ears from bleeding. Hikaru sounding 40 is bad enough, but Sai sounds absolutely ridiculous. WHY, VIZ, WHY?
