Seriously, I found it really off beat when suddenly Su called her out by name and she had an actual line. Along with ominous music.
Me: Okay that was weird, anyways back to Zaheer!
What character was really set up, though? I mean, we have everyone from the creators, to the actual show all giving us mixed messages about who the hell Kuvira actually is, and what we get in the end is this mesh of the Good Hitler, scared little girl, manipulative bitch, iron lady, and we're supposed to buy this with the lack of any connective tissue between any of it? Fuck off Bryke, stick to one and develop it. You CAN have all these things, they didn't do jack to develop it properly. Yeah, even the Giant Killer Robot from Space.
Yeah the tone is what ultimately didn't work when she gave her response in accordance to what just happened before. Kuvira is BAD, and should get properly punished, but in that moment, you're like "Well damn, Su."
