First, the fiction: Perhaps the premise is a little contrived. Channeling the spirit of a famous Victorian woman into a PC (and more than the PC) is a bit improbable. Fine. Once that premise is in place, the plot stays within its own inner logic and moves forward quite well.
The reality, though, is what struck me. First, there is Ada herself. Yes, she was brilliant. She made a place for herself when all the places were reserved for men. We've heard that part. She was also a real, flawed human being, with a destructive gambling habit. Much of her interest in math and algorithms was centered on finding "the system" for beating the odds in horse races. Her creation of programming was driven by an urge that she could not control - like a flower that blooms because it grows in manure.
Emmy seems real, too, a fully mature "geek girl," but drawn with respect. She's intelligent, wholly wrapped up in her work, and also driven by a vision of her own. Best, she is completely a woman - not pretty, but beautiful, and not just a male role with a female actor. Emmy represents a character that I know and admire in real life. This is the first time I've seen it portrayed on screen, or at least portrayed so strongly.
Finally, the ethical question of Emmy's daughter is very real. The exact circumstance, as I said, is fiction. The issue is not: We have unprecedented control over what a baby, a new human being, can become. What kinds of control are morally acceptable? To tell the truth, I think Emmy took "what we can do" well past "what we should do."
