Okay I'm just going through Season 1. It's okay. It has a cohesiveness in a series that I really like. The episodes just appeared standalone at first but drop hints that are followed up.
Haven't really got to an episode that has completely hooked me yet. Well maybe the "Signs and Portents" one. Haven't seen the last two yet.
Some characters are better than others. G'Kar (who I think I love) and Londo (?) seem more interesting than the Minbari ambassador.
Have to say I really applaud the creators for trying to get some non-human lookalike aliens in. The Black Market dealer for instance.
Also like that the station is more like a city and there's parts that "respectable" people don't go and parts where the commander isn't even recognized. Good stuff.
