Too edgy and too smart for the average TV audience.
This show was wonderfully acted, intense in many places, well cast, and it just simply went over most people's heads. It wasn't gritty or set in space and the themes of terrorist attacks and zealous religion really turned off a lot of American viewers and that's sad because we should be able to have shows that can show those things or talk about those things without being people so sensitive. I remember TONS of newspapers and magazines saying 'how dare they' or 'this is offensive' when the show came out due to the kids who suicide bombed the train. It's disgusting people lambast entertainment because something within it offends them. This show was *beep* ART. Every episode was good and for most people who say it was 'slow', so what? Game of *beep* thrones is slow. Walking dead is HELLA slow (almost nothing happens in most of the episodes), people just wanna hate on something because it's not what they expected and get too stuck in the linear mindthink and it sucks because this show was as good (if not better) than BSG as a whole and I *beep* LOVE BSG. This should have had at LEAST two seasons greenlit before even filming and sometimes Syfy, you gotta take a profit loss in order to pump out some *beep* gold, all the channels and studios do it now and then, you can make up the difference with your *beep* WWE money.
