Sure, there were happy moments. I was raised in the JWs and cannot truthfully say that it was completely backward. I still grew up loving Star Wars and eating pizza, but the bad, over-all, outweighs the good.
I must say that I appreciate a few things about my JW experience that are directly as a result of being a JW. For starters, I have almost no fear of public speaking -- at all. Even though I was spewing out twisted JW doctrine (I tried to make it sound logical and fun), I at least had the opportunity to speak in front of an audience two or three times a month. Plus, pioneering for seven years helped me develop my one-on-one speaking skills. I also learned a great deal about the Bible (however a parochial view that was) and organizational procedures in general. I'm also thankful for the friendships I had when I was in, even though they are lost now.
On the other hand, practically everything I just mentioned could be said about a number of other religious groups, like the Mormons. Also, there were plenty of things that I didn't get to do that I'm paying for now.
Once history takes it's course it's hard to try and imagine a re-write of it.
