I don't really want a future for B5. Time to let it rest.
See, I have a different perspective on this, which is that if we let it rest, it becomes forgotten about. Whatever you thought of The Road Home, its release and that of the Blu-ray boxset in 2023 both gave B5 a real shot in the arm. More people started discovering, or rediscovering, the show, and brought in new fans. Yes, the follow-ups and additions to the main five-year story have been of variable quality, but let's not kid ourselves into thinking JMS hasn't done anything of note since B5 and that any revival is bound to fail. The man can still write.
From a personal perspective I also collect memorabilia, nothing pricy, just trading cards, action figures, autographs, etc. Other shows from the 90s and earlier are still getting new memorabilia released, but B5 gets nothing. A new show, a revival, would increase the chances of new stuff getting made.
But most importantly, whatever the quality of a reboot, it would keep the memory of the original show alive.
Or we can let it rest, complain about any attempts to revive it, and its legacy fades away as it becomes nothing more than another forgotten show, which is the way it was headed prior to the remastering and the release of The Road Home. Given how important B5 has been in my life, I don't want to see that happen.
Also on a personal level, he should take it easy and enjoy life. Not saying put himself out to pasture... but do interesting projects not get into the onslaught of weekly TV again for years.
If the reboot did happen, it'd probably consist of seasons 6-8 episodes long, all written before shooting begins. That seems to be the way of modern TV now, JMS wouldn't have to complete the same kind of marathon that he did in the original run. It might make a reboot more manageable.
