Agreed.
I was bitterly disappointed with the finale. I really liked the Greek polytheism in the series because it brought with it a rich history of dramatic storytelling, but at the end it just did a hardcore nose dive into modern, literal, monotheism. I am surprised the last episode wasn't sponsored by one of the big media savvy branches of Christianity.
I liked the symbolism of human history being cyclical, but again, the show went for literalism in ALL CAPS. Shirking off modern technology obviously wouldn't break the boom and bust cycle of civilizations be it literal or metaphorical. The implied universal abandonment of technology was a gross miscalculation in the understanding of human nature on the part of the writers of the show. I imagine the first action that separated prehistoric man from the animals was the first time one human killed another for no better reason than anger or jealousy. Those "peaceful" prehistoric humans they observed were likely already using their tools to kill each other, and its just plain idiotic to think that abandoning electricity, and medicine, and written language would somehow remove the anti social and violent tendencies which seemed abundant amongst the crew of BSG. And of course, advanced space traveling future/past humans would be naturally suited to go full stop and adopt a nomadic salt of the earth subsistence lifestyle with no tools or know how in a matter of hours.
BSG was an otherwise great TV show, but the last half hour of the series really did grievous damage to the integrity of the story, it was painfully apparent the "geniuses" behind the show had no plan whatsoever and wrote themselves into a corner and used religion as a cop out.
Also, was this the first episode to involve time travel? And lastly, it was stated that Hera died as a child, is that compatible with her being" Mitochondrial Eve"? Who did she mate with...as a child... I really don't think the very last bit showing the present was necessary at all.
