B5 is one of those shows that addresses lots of social issues. In a way that isn't remotely offensive (ok, the pak'ma'ra are really gross as they are carrion eaters, but they handle even that well) Season 1 is really slow, and they change the captain the 2nd season and I think it really gets better from there. But, hang in through season 1! There is even a small, tiny nod to bisexuality. :-)
