Absolutely loved B5, so much so that when they aired the final episode on channel 4 many moons ago I went out, and over the course of a year, bought every single VHS of all 5 seasons and movies, considering there were 2-3 episodes to a VHS there were about 50 of them in the end.
Id never seen a sci-fi before that was set more like a soap in space when compared to Star Trek where every episode was different and usually bore no relation to the previous one. You really got to know every side of the characters and it was funny as well, but not in a cheesy sci-fi way but in a well written sit-com way.
Awesome show, just a shame that Crusade was so poor in relation, but I find spin-offs generally are.
