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
