Its not really bullshit. I mean...what Itachi did with implanting an eye technique into Sasuke's eye to go off if he comes in contact with Obito's Sharingan, that's far more farfetched than what Madara pulled, and we accepted the first one easily enough. Same with Obito, if you stop to think about it...
Mind you, there is still plenty bullshit left in this series. Sasuke escaping Deidara's blast, Itachi pulling Izanami off his ass, Black Zetsu's betrayal....I just don't think these are part of it..
I didn't mean BS ash in unbelievable, i meant BS as in overpowered and underutilized.
example. why did Madara not use Izanagi after Black Zetsu stabbed him? there was a moment in time where he was perfectly mobile before transforming...
I do not think Izanami is an assail either, considering anyone who knew a thing about Japanese culture would see it coming. it is no more an assail than the invention of Izanagi, an ultra powerful Genjutsu that warps reality that somehow we are just now hearing about, and somehow was not used against Itachi and Obito during the massacre (really, you could kill someone you thought was asleep, and then they appear with a sword in your neck. There is no way every single person was asleep, there was SOME resistance.)
As for black Zetsu... yeah... should have at least been hinted at in some abstract way, it really felt like kishi was like "lets make a stronger villain! But... Madera can't get stronger... ooh! turns out, black zetsu was really working for this alien princess who is the SO6P mom, and the true origin of chakra!" not that her mythology doesn't fit in perfectly though, cause it does... so maybe he DID think of it a long time before, he just failed to write it in properly...
