I'd say the Samurai Champloo ending was good, in my opinion it pretty much the most natural way for it too end although i have heard a lot of stuff about how it was anti-climatic, but it really just fits the mood of the show perfectly...laid back

I also think the S-cry-ed anime concluded alright, it didnt cover the eintire manga by far but the last ep with Kazuma and Ryuuho doing what they do best was pleasing enough

And can someone please tell me about their thoughts on the endings of Peacemaker Kurogane and Black Blood Brothers, they way both way too unresolved
