I recently bought the entire series on DVD and watched the pilot episodes. I thought the first pilot where the characters had different names was better than the second pilot with a different actress playing Chrissy. However seeing both pilots, made me see how much better the series actually was when it got started and with Suzanne Somers as Chrissy.

It was cool seeing how things could have been with the show had the producers made different decisions at the time. The shows we know today never would have came to be.
