i think, by far, the DVD collections of Dragon Ball Z and Yu Yu Hakusho (both by Funimation) were the best anime things we bought this year! with those things, you're collecting history~!
^_^ the quality of the re-touching and dubbing really push standards when it comes to revitalizing anime, and with the DBZ version, the multiple language option really made it something special. you could pick the full on Japanese soundtrack (voices, music, everything), the English TV version (what you saw on Cartoon Network), or English with Japanese sound track. for me, that really put it over the top!
as for YuYu, i had always known the show was good, but since they re-did everything, the quality of the story really shines through. and the fact that the first 3 DVDs came with chibi keychains of that characters helped a lot too!
all theshows mentioned here were un edited, so getting to see all the blood gave a new feel! especially in DBZ! people actually... were like, murdered or something! Frieza actually killed everyone! you didn't see that in the CN version!
