Having given you my favorites and given the depth and scope of this tale I suspect some episodes that I may have discounted might benefit immensely from a second viewing. These are my favorites based upon my initial viewing and my fading memory. Also, of course, none of these episodes can be completely appreciated or fully understood outside of the entire scope and framework of J. Michael Straczynski's deep-thinking saga Babylon 5, which is why a second viewing might just change things.
If you have a moment I'd love to see where your BIG 10 for Babylon 5 rank.
