Yes, that that was the generally received interpretation for a long time. More recently, female critics have been looking at the story with some different ideas. Mary Shelley was, after all, a woman and a mother (albeit of a stillborn child), and may have had different attitudes than a man might have about "creating life" and the responsibilities that come afterward. She also had some pretty interesting issues with her own parents, both the father who was still alive and the mother who died soon after she was born.
Anyway, the myths about Prometheus never say that he was wrong to do what he did -- just that he was punished for it. So calling Victor Frankenstein a Modern Prometheus doesn't necessarily imply a moral judgement of what he did.
More to the point, I'm not even sure what I think Mary Shelley intended; it's just, like I said, an interesting question.
