A surprise addition to HBOmax: https://www.comicsbeat.com/fandom-flames-babylon-5-remaster/ For any who have never seen the show, I recommend starting with season two. You can go back later and watch season one as a kind-of prequel if you want; but you’ll enjoy it more starting with season two.
And the last season was kinda crappy. They were told they were cancelled so they finished the main story arc and did a great job of it. Then, "Hey, we're giving you another season!" So they made an add-on story which wasn't very good. The last episode though was excellent.
