I didn't like how not one female character was treated with any real importance, they were all expendable, Angier's wife killed( murdered?), Borden's wife( suicide), and His daughter and Olivia were only treated and used as pawns.
I also did not think Borden and Fallon were clones, but blood relatives even though I don't recall, but perhaps it was said or implied in the film I just didn't pick up on it being told to us outright. Just sort of assumed, until you see Angier creating and creating and creating many doubles of himself.
