I love this show but apparently few others like it. Can't even convince my family to watch it. CGI is amazing. I say this because I can only tell that it was used due to the impossibility of the scenes - not because of obvious visual flaws. The settings are grand and awe inspiring. Sort of the opposite of the sometimes claustrophobic old Doctor Who's or ship borne original Star Trek's. Despite reviews here, writing *is* excellent from both a character development and science fiction perspective. Acting is good except for Parker Posey who seems compelled to try and steal every scene she is in. Never understood why she is worshipped by fans of Indie films. Blech. For me this is one of those shows where I think it is about to plateau (or crater) and it just takes it higher. At the end of each episode I'm a little sad because I am closer to the end.
