felt the "sense of danger" when Obito became a host to the strongest being in NV then ....................... it turned out to be a huge disappointment (lost to the "power of friendship" ............... am speechless), Naruto keeps getting chakra from thin air, no one is dying (edo's) so what did you expect ??
Well the total loss of free will 15 minutes was the real danger .... Obito was mostly toying with the alliance and occasionally using them as Sinju manure or trying to wipe them out when he is annoyed ..... Killing the alliance was never 'have to do' his target: He continuously asked the alliance to accept his path ..... he seemingly wanted validation of his chosen path and the alliance giving into despair would just confirm his ideals are right.
To add on to what i said.. everyone of you guys know you read Naruto to see what is going to happen next so you can "evaluate" it. Its not like you guys are thinking " Ok sh*t man i hope next week , Naruto stops Obito". The mentality of the fans has changed.
