Probably the most politically relevant show about the worlds post 9/11 point of view, but people refuse to acknowledge how good it is. Why? Puiely because of its name. Its my favourite show ever, and thses include shows like Sopranos/Wire/WW. Its the only show to win a Peabody.
Battlestar Galactica? The name is the only reason it isn't extremely popular.
PS DS9, if it was actually original and not a ripo off of a ST idea is better than B5
