Gotham's synopsis doesn't seem radically different from other interpretations of the character. (Like Batman: The Animated Series)
Sounds pretty good to be honest.
“Though ferociously smart and eminently capable in his work as one of Gotham’s preeminent cryogenics engineers, Victor struggles to make meaningful connections with others. The one exception is his wife, Nora (casting TBA), who has tragically fallen ill with a terminal disease. Victor’s love for Nora knows no bounds, so as her condition worsens, he goes to extreme measures to figure out a way to freeze her before she dies. This harrowing journey leads to his transformation into the legendary DC villain, Mr. Freeze.”
