I liked how everything ended, had issue with a few things, like sending their technology into the sun and no one complaining about it. I would have expected some conflict. Of course, they had no time for that, but still, then they should have done something else. I do understand why some would want to put blame on technology, it is also not the first time they do it, they did it during the first cylon war. I just don't understand how everyone would agree to it in unison and with no conflict.
Also, talking to Rugen he brought up some things about Baltar and now I sort of don't like how Baltar ended. All he did, the many times he betrayed and killed members of his own species and he is somehow a chosen one? What did he do to redeem himself? Feed some hungry children? That's it? Uh... ok. The God in this story turned out to be as fucked up as the one some people worship IRL.
I didn't mind the mythos at all though, I kind of liked it. I liked the idea of the angels, and I didn't mind Kara ending the way she did. It was kind of neat, somehow. I do feel they used all of this as an excuse to be lazy, they could have done more with it.
I sort of wish they would have landed a few thousand years later though, I understand why they wanted them to land at the time they landed, but... it doesn't make sense that present time Earth would have turned out to be the way it did in the end with them landing so far back. They must have given up their technology, but they still kept their brains and knowledge about things. There were still architects, dreamers, etc. In other words, present day Earth should have been much more advanced if such an advanced civilization would have landed at the time they landed.
Then again, maybe the early modern humans killed all the BSG humans, kept some women around, mostly children, one of them Hera, and raped the heck out of them and voila, her genes passed on but not her culture. But, yeah, this is my only huge pet peeve about the finale. =P
