Have to say I found the ending disappointing. The whole idea that we evolved from both native, Colonial and Cylon forefathers felt wrong and to unbelievable. Secondly as a non religious person all the religious 'God' clap trap was boring, stupid and offensive to me. I wanted to know how Starbuck susrvived the implosion not rubbish about 'God's Will'.
They put too much emphasis on this Watchtower song! I have never heard of it and so all the hints/clues/meanings were lost on me. It meant that I had no idea what they were going on about at times (still don't).
The idea they were pushing that Hera was somehow the ancestor of the human race as a "Mitochondrial Eve" was based on completely wrong science so made no sense whatsoever.
