You're right about the killing curse, of course. I was just so fed up with the whole rescuing the damsel sequence, and that highly disturbing way in which they handled the death sentence, I didn't think of what you mention.

I could buy the plot better if Newt was pants at things that Muggles consider basic. But the strange thing is, he's pants at something that's vital in the Wizarding world, i.e. keeping magic away from Muggles.

The images were beautiful, though. Visually it's an absolute feast for the eye, and I did like the Niffler. Such an endearing little chap.
