SPOILERZ
I finished last night, and was pretty disappointed. Honestly, it feels as though the series was incredible for 75 episodes, and the last just completely sunk my attitude. The last episode introduces too much confusion [teehee] for a respectable conclusion to such a tremendous series. First of all, no satisfactory explanation to Starbuck's resurrection and disappearance, but that is minor compared to the clusterfuck of inconsistency that emerges from humanity's decision to go back to basics and mingle with the humanoids they found on earth. I can barely stretch my bullshit threshold enough to accept coincident humanoid evolution across millions of light years [this absurdly implies homo sapiens is the inevitable evolutionary track for life given a certain environment] and they satisfy the astronomical chances of such an occurence to divine will :/ , but I can't make the leap to think EVERY human is okay with completely abandoning their technology, culture, ways of life to go back to shitting in huts for 150000 years. No written word, no art, no metallurgy, no agriculture [although Gaius wants to farm, TOO BAD HE CAN'T DO THAT FOR 140000 YEARS OR HE MESSES UP THE ANTHROPOLOGICAL TIMELINE]. The idea that 40000 or so humans would be able to forget their cultural knowledge to the degree that NOBODY tries to resurrect the old ways of their lives is incredibly insulting. By tying the series into our real universal narrative, they de-legitimized their own. Just terrible.
Although I was happy Helo and Athena had a happy ending. What can I say, I'm a huge sap.
