But Hinata is not like Minato at all -___-
Minato is quiet, calm, intelligent and collected, but able to speak for himself when he wants to.
Hinata is not quiet, she is shy. She has a problem with expressing herself.
She is not intelligent either. When did she make a strategy? Never 
Even when she had the ability to, Katsuyu(whos task was to share information about Pain to all shinobi) was right beside her before she jumped in to die with Naruto.
She's not calm, she gets nervous whenever Naruto is in the slightest danger and almost fainted when he fought Neji, also silently begging him to give up.
Hinata could've been this confident girl that progressed from part 1, but she's only able to be one when she's in danger or a minute after Naruto has encouraged her. When she's has used up the temporary confidence from Naruto, she's just a timid girl in the corner to me.
