Bigger picture
Danny in the past has shown signs of potentially going a little too far to extremes when dealing with admittedly bad people. And if she didn't have her council of advisers in place she likely would have went way too far already. The shit that Cersei was saying about her in the Throne Room was Fox News'd a little but wasn't exactly a lie. She's starting to ignore her own council again. In this episode she wanted to take her dragons directly to the Red Keep and burn the entire place down simply because her ego was bruised from taking a couple of losses, and needed multiple people to talk her down from doing that. Instead of taking her dragons directly to Kings Landing and scorching the Red Keep, she took her dragons directly too a food supply chain that both her forces and the average people of Westeros needed in order to survive.
What Danny did was impulsive and incredibly short sighted because what she did is almost certainly going to affect the general people of Westeros way more than it's going to affect Danny or Cersei or their respective forces. Everyday people that Danny is trying to liberate are now going to potentially starve and suffer because Danny wanted to heal her bruised ego. That makes it sure seem like she's got more of her father in her than she wants to realize.
