I think I know the series of decision that lead to the disastrous Battlestar Galactica finale. The dominant narrative is to put the blame on a lack of planning. That's incorrect. Lack of planning did lead to some questionable decisions (making football guy a Cylon did not make him more interesting), but the series is not a mystery. Only the intro insist the Cylon have a plan; the human characters do not suspect it and the Cylon never behave as if. The problem is the opposite. The writers have a specific conclusion they want to reach, and are doing anything to get from point A to point B. The real culprit is the very mandate of the reboot to make a grounded version of the 1978 series.
Three things influenced the original Battlestar Galactica: Star Wars, the Book of Mormon and Chariots of the Gods? ("There are those who believe that life here began out there [...]"). From season one of the reboot the characters are following prophecies and witnessing signs from the divine which eventually lead them to earth. This is simply the result of melding influence two and influence three, because they are the same story, only instead of the Toltec, the reboot mention Mitochondrial Eve. I have seen people say that Starbuck resurrection is "unexplained", but I disagree. God did it. That's what the show says. This is not poor planning, this is a continuation of the story they have been telling from the start. The poor planning part is when the colonists decide to abandon all technology because a "clean start" can only be achieve without penicillin.
It's a neat logic leading to a series of bad ideas. I'm an atheist, so I don't resonate with the message "only by trusting in God's miracle can we escape the cycle of violence." Maybe we can't escape the cycle of violence. Also, what does "every modern human is a bit Cylon" says about us? The best "Just so" story have a message. So we're all a bit robot. Okay. What does that mean? Why should I care?
The Battlestar Galactica achieved the goals it set out to do. It never questioned if those goals were worth achieving.
