Re: DC's New 52: Reviews and Discussion (Spoilers welcolme and likely)
Ok, so Batman Annual #1 does some major revising to Mr. Freeze's origin. I'm not quite sure I like it.
Basically, Nora was never his wife. She's someone who was frozen decades before, and that Fries had a creepy crush on from working in the cryo-lab where she was stored. Also, he murdered his mother as a child after she had an accident that left her unable to walk, and no longer right in the head.
Essentially, this changes Freeze from a tragic, and sympathetic villain into just another evil nutjob in Batman's rogues gallery. I know the previous origin was only first introduced in the Animated Series, but it was a good origin. That's why it bled over to every other format. It gave the character some depth, and made him stand out. We actually felt some sympathy for the villain, even if he was doing terrible deeds. That's gone, now.
