Like most space opera/sci-fi opera of those years, the writing has periods of greatness and mediocrity. I had the whole thing on DVD at one time, including the movies (same with Stargate SG-1, Stargate Atlantis, and the earlier Star Trek movies). It isn't easy or simple, in my opinion, to get that genre to work over many years of production; if you want to avoid other cultural issues. I will say, though, taken as a whole, Babylon 5 and Stargate SG-1 were good.
