Yeah aside from the hard continuity issue where the main character's actor in season one developed mental illness and had to quit - one of the most engaging sci fi universes
They really go into ideas that other shows skim over, like aliens having to breathe different atmospheres, being radically different lifeforms that need mysterious suits to interact with humans
The show is primarily a political drama, which is actually refreshing. It's not all shootouts, it's a lot of diplomacy. But not so incredibly serious that it's tedious, Babylon 5 is often comical, with its outrageous alien characters
Basically a hidden gem, maybe on par with Andromeda or something. A unique b-list cult series. Has been a few years, might be time to watch it again for me
