>I would give my left kidney for either a continuation or a reboot of Babylon 5 under the helm of J. Michael Straczynski with full creative freedom.

I don't know. I loved Babylon 5 but I also found it kind of corny. And then Crusade was just a D&D campaign in space. The ship was even called the Excalibur FFS. I feel like "full creative freedom" would ruin it the way it did with George Lucas and Star Wars.

>and I wish more writers/showrunners would adopt this approach (instead of the usual writers' room + only plan until the end of the season approach which is so common today.

What else can you do when you don't know if you're getting renewed? You can't push the conclusions to your storylines forward into seasons you might never even have to resolve them.
