It is unfair to rate this special if you don't consider everything else, so I couldn't give it a low score because Yuu Yuu Hakusho is one of my all time favourites. Both episodes are well animated and drawn, the first episode is okay to put in context Hiei's and Kurama's alliance, specially when Hiei points out in the anime's beginning how fearsome Kurama is despite his looks, the second one felt like a filler, it is okay but at least we got to see our favourite characters again. The worst part is that we get that nostalgia feeling and we want to see more, it woulde great to see more, but the anime ended perfectly and I wouldn't want to spoil that either. Anyway, I'll bear the pain and for this 25th year anniversary I can only say

ARIGATO GOZAI masu!
