Just saw the video. The woman appears to be wearing a neck brace on top of everything else and she was smiling like this was all just joking around until he grabs her by the brace, she gasps in surprise and pain, and he takes her to the floor with someone grabbing him and saying, "Whoa, bro".
The WB's attitude seems to be that if they respond, it will escalate the situation by making many times more people aware of it while it will fade away if they ignore it.
To me, Ezra Miller's Flash is kind of like Austin Powers. He was funny at first but it was wearing thin before even the first hour was over. I never saw the second or third movie because I had already seen the same one trick pony skits two dozen times in the first movie. The very fact that one can so easily draw a parallel between Miller's Flash and Austin Powers is telling in itself.
While it can be said that none of the television versions are what the comic book Barry was, especially originally, I liked the 1990 Flash and love Gustin's Flash. It isn't so much that Miller doesn't come across as the comic book Barry but that his nervous comedy routine just doesn't appeal.
It makes me wonder why I loved Jerry Lewis movies and Barney Fife but I think the answer is that I was five when I first saw them and nostalgia rules. Or maybe they just did it better.
