While I haven't been able to purchase the Basilisk anime yet I have been reading the manga. So far it's been pretty good except for one thing in volume 1 (Possible Spoilers begin here).......
........In the manga, Gennosuke and Oboro's respective grandparents Danjou and Ogen were in love during their youth
and attempted to bring peace between the Koga and Iga clans. Unfortunetely, the preassures from both sides became too
much for them and they forsook their love. Fast forward to the time of the main story; after agreeing to lead their
clan's elite 10 against each other, a sneak attack by Danjou on his former lover ends in both dying. As they both
pass into the afterlife, the manga depicts them in their youth and lying together, signifying that in death they'll
be together.
The reason why I dislike this particular scene is because I don't feel Danjou and Ogen deserve to be together in
death anymore than they did in life. They both chose their clans over each other, and in time were perfectly willing to
kill each other in the name of their clans(Ogen even cackles vindictively when she kills Danjou). And they certainly
don't deserve heaven as they willingly forced the same suffering they experienced on Oboro and Gennosuke. Although
this scene is quickly forgotten as Basilisk's plot gets underway, for the instant that it occurs it succeeds in
turning Basilisk from a tragedy into a farce
