I was never a huge fan of the retooled Battlestar Galactica, not because it wasn't a good show, but because it didn't entertain me the way I want to be entertained. Overly complicated, often too preachy for my tastes, and with no sense of humor about itself or anything else, it just never quite managed to be my kind of show. By the time the last few episodes rolled around, I had lost interest in all of the characters, because there was nobody left that I found likeable at all. But then the plot started drawing me in, so that I had to stick around just to see how they managed to tie everything up.
Happily, they wrapped things up fairly well. The seemingly incomprehensible plot threads that were strung out in Season Three actually managed to weave together in some semblance of order, and the final ending brought everything nicely full-circle. I wasn't entirely sure what the final message was meant to be, though. Would the changes and knowledge that occurred during the Galactica's journeys prevent history from once again repeating itself, or is humanity following the same path of hubris and segregated prejudice that led to the original Cylon War? The answer remained unclear, and I'm still not sure if that was deliberate or a slip-up in otherwise fairly solid storytelling.
