Abner Kravitz was a pretty good man. He just had an unbearable wife. I think all in all, I would vote for Sam's powers, if only because she wasn't a slave. Dr. Bellows was a little smarter than Tate, it is true, but he was always foiled in the end. I even thought his wife was pretty hot for an older woman -- a hint of daring in her eyes. But I guess we don't need to go there. Bottom line, I'll take Sam.
I think Gladys was the best character on that show. I'll take Jeannie. Belly Button exposure censure and all, but both her and Sam have qualities today's women just don't understand.
