I like Babylon 5, it had Bruce Boxenlietner and Jerry Doyle, both of whom are conservatives and very good actors.
Not to mention very good roles by Peter Jurassik and Andreaes Katsulas. It deals with politics very impressively.
It shows the two forces at work in the cosmos, the Shadows (disorder) and the Vorlons (order).
The Shadows are of the Anarchy and disorder variety and the Vorlons want to be your parents and tell you what to do.
Babylon 5 was excellent! Once the story arc became evident, it was a must see.
