What I liked most about this opening is the mutliple nods to the manga,
the green jacket era and even a few Miyazaki bits. Plus the animation doesn't shy
away from the raunchiest elements of the saga (sexuality, violence etc.).
I haven't watched the special yet but even if I know it re-uses footage from the series (at least
some we already seen during the italian broadcast), I'll take it as it is. ^^
