Not just good Sci-Fi B5 is not only one of my favorite Science Fiction series, but one of my favorite series overall. The story is told over a five-year arc, which is unusual and very risky in television, where renewal for another season is not always a given. Because of this overall arc, it's not a show you can pick up in the middle and be able to follow. It must be viewed from the start and in order, as there is a certain progression of events. The writing is very good and each of the main characters is given ample screen time to develop over the course of the series. Don't be put off by the fact that it's science fiction. It's still, at it's core, a story about people, each of whom has real feelings and hidden agendas, much like real people we all know. These people just happen to live on a space station 200 years in the future, but the themes are timeless; loyalty and betrayal, personal conflict and redemption. As some have noted, it starts off a little slow in the first season but by the second, the various story lines start rolling right along to their various climaxes, interweaving in very intricate fashion along the way. It is certainly worth a look if you aren't yet familiar with this largely undiscovered gem of a series.
