"Where do you stand on Samantha vs. Jeannie for superpowers?"
Definitely Jeannie. Only good thing other than oil that has come out of the middle east in the last 100 years.
I think Jeannie was less prone to breakdowns in her powers than Samantha, who often needed Dr. Bombay to break a hex or get rid of some weird spots on her face. On the other hand, Jeannie was always being ordered back into her bottle by Tony Nelson. I don't think he played his cards quite as well as sophisticates like you or I would have.
