I like both. I would start the early years December 7th 1941, or on the day the stock market crashed, in keeping with the idea of starting a series on a historic day. I would rather see the 21st Century one, because it would be cool to see what all the characters are doing. On the other hand, we never really heard much about who Helen was before she met Jack. For the early years, it would have been interesting to see Henry in an all-black unit. They're both interesting ideas to contemplate.
