also, wtf was the point of all that training bullshit Naruto had to endure to control Kurama's chakra if Minato could do it just like that, in the blink of an eye? It undermines anything the protagonist has ever done to the point it makes you wonder whether he was just supposed to be retarded or the result of dreadful, nonsensical writing.
Don't get me started on Sasuke's 180° then...I'm not even that much of a fan and only started reading the manga after the time-skip but this is just silly on so many levels I'm at loss of words, goes to show that most mangas are just kids stuff and that's about it.
