Just saw DOFP for the first time. It was good, but not really even as good as First Class. Only thing memorable from this movie that stands in league with First Class was the Quicksilver stuff.
I agree with your reasoning about the BS Kat Denning comedy crap, but that scene was poorly choreographed. I can see what it was trying to do, and the idea was cool, but I can see why it was cut.
Re: Batman vs. Superman (2016)
Are you still seriously trying to pick apart the scientific reasoning...from a movie? Superman has the McGuffin, the bad guys want the McGuffin, punching ensues. End of story. Move on already.
