I'd struggle to watch Babylon 5 I think.
I didnt watch DS9 until 2003 when the DVDs were released and I thought it was great - I started watching it on Netflix last year and though it is still great, the standard definition fuzzy picture, cheap sets and (mostly) very dated CGI have not been kind. Some of the stories are quite dated as well now, it was constrained by the network and decade it was shown, but TV has gotten enormously more complex since IMO.
Crusade was basically him trying to do a B5 story, whilst the network were trying to cancel the contract for "cause" by forcing him to make major changes whilst it was in production, including sexier characters/more skin and a simpler story to make it more appealing to the sort of people that liked their female characters wearing bikini armour and more explosions or shoot outs with less story (they'd signed based on B5's success but different execs took over and wanted sexier and simpler or better yet to kill it off).One thing that worrys me. He made Crusade after b5 and well i dunno about the rest of you but i thought that was pretty bad, i didnt like their casting which is probs a big reason why i didnt like it but also it didnt follow very well in the episodes iirc and it was never concluded as it got canned. So if he made and wrote Crusade, does he really have it in him still to make something like the original b5 concept and pull it off?
Also i wonder what the budget is for the new b5, will it be a mill per episode, or more? I think when i was watching scott bakula interview lately he mentioned enterprise was around near 2 mill a episode i think and the last season about 700k pe.
JMS is behind the reboot,so I am hopeful its fine as he created the series and wrote most of the episodes!
This is a really good website if you want to look at some of the original concepts behind the series:

One of the people connected with that website,got hold of the original CGI assets,and re-rendered them on a modern system:

Considering they are 26 years old,they still look pretty decent IMHO. There also seems to be a better master of the original series too on HBO Max:
That looks epic!
go to youtube and search babylon 5 4k, theres more great rerendering vids using original assets, theres one that does a lot of the big battles too which looks great.

I think anyone but CW and i'd be mildly excited, however B5 is my favourite sci fi show of all time and as such, no matter how good this is, i'll be unfairly comparing it all the way through.
Is it unfair to think someone can make something better 30 years later? If they can't make it better (so by definition just make it worse), then they should leave it alone. I don't think you're being unfair to compare a new B5 (with nearly 30 years of advancement), to the original version. If it can't surpass the original, then don't make it.
Just already feel like i'm not giving it a fair chance as I don't believe they can improve upon the consistently good performances across the majority of the ensemble cast. That's my biggest gripe with this reboot, even if they got a handful of great actors, B5 was lightning in a bottle with it's casting, to do that twice would be something to behold.
