Thanks everyone. All of these answers make sense and I'm wiser for being here.
For the record, I never watched more than two isolated episodes of B5. Both times nothing made any sense to me and it was like being in a room full of people all sharing inside jokes. (Now that I think about it, it's a little like following politics.) Having learned more about the series and how it was constructed I am interested in starting from the beginning to see what it's all about.
