Well, I liked that when the "thing" that Daenerys had so hinged her identity on was threatened, she dropped the "false veneer" of principles and revealed herself no different than any other tyrant.
What I didn't like is how they go there. Or, rather, just arrived via dues ex machina really. Actually, maybe not even that tenuously at all, but just spontaneously, as if from no where.
At the very least, they should have actually shown people rallying to Jon calling off the attack and standing down. That would have at least been an actual catalyst to spur her to force the action, invoke the fear she feels she had to, to enforce her will over Jon.
Instead we just got nothing.
