I watched a two-hour episode titled "Pilot". Is there more to the pilot than those two hours?
No, those two hours are the whole pilot.
I suppose the thing that jumped out at me the most is that it's little more than a "Frankenstein" remake....
I think the important difference is that this time, it's the creator -- or rather the creator's father -- who starts out as a monster. The machine, by contrast, starts out as a nice, sensitive being whose self-image gets shaken horribly. There's a distinct scent of Kafka in the air: "When Gregor Samsa awoke from troubled dreams one morning, he found that he had been transformed in his bed into an enormous bug". Just substitute "Gregor Samsa" with "Virtual Zoe", and "bug" with "killer robot". That gives you her side of the conflict right there.
This is an important element in Caprica
you don't have in Frankenstein
. And that, in my judgment, is where the conflict underlying the series goes way beyond the conflict underlying Frankenstein
