Just saw this great thread. Bewitched is a fascinating topic for me, for several reasons.
Mainly, I see it as an allegory with a feminist message, whether deliberate or not. Samantha had powers that she wasn't allowed to use, under orders from the patriarchy, aka Darren. She was obviously smarter than Darren, even magical powers aside, and with her powers way outclassed him in all other skills. Darren forbade her to practice or reveal those superior skills to anyone, and she willingly complied, embracing the role of happy devoted housewife except very occasionally, when required to avert disaster, usually caused by her own relatives.
Bewitched began in 1964, the year after The Feminine Mystique was published. It ended in 1972 -- two years, for perspective, after The Mary Tyler Moore Show debuted. Bewitched, with that premise, could never, ever air today. Whereas in essence TMT is really a less-funny 30 Rock (think about it! you can even see parallels among many of the cast members, though Liz Lemon = Mary + Rhoda).
Even as a child watching Bewitched, I was always baffled that smart, cool, beautiful, magical Samantha would marry (and obey!) dorky dimwitted Darren. I thought her evil twin brunette cousin Sabrina had made the much better lifestyle choice.
The show is also fascinating to watch because it's so full of anachronisms, not just sexist ones. In one episode I saw, in addition to Samantha having to beg Darren for money to buy herself a winter coat, we saw Darren's use of both sides of scratch paper as evidence that he was under a spell that made him absurdly frugal, and when Samantha told him she was planning to make chicken when the big client came to dinner, Darren, still under the frugality spell, ordered her to make something cheaper, like veal.
