I know iz not a book, but it is the most recent work in the genre that I've spent time thinking about and I have a strong opinion about it so I thought it'd be a good place to start.
The ending sucked.
First of all, did anyone else see Cavil blow his own head off on the CIC at the end there? My first reaction was, "That punk can still download!" If he can't still download, what was he doing? Was he afraid the humans and cylons were going to torture him? Kill him, yeah, I see the cylons killing him, but not likely to torture him. Although, I guess iz fair to speculate that he was paranoid enough to think that he might get tortured, so I see him taking that way out. But his character really did seem to want to live so I was still surprised by his choice.
As for how the series ended, there were so many different ways to offer the same end result and, me not being a religious person, I found the choices the writers made to be most disappointing. I know that there are still a couple pieces of the picture still yet to come, (BSG: The Plan), but if we look at the series as a whole their are still some things that were done that demonstrate what the writers decided on as the resolution.
1) Yes, I'd loved it if they'd revealed Kara as the daughter of cylon Daniel. To me, that makes the most sense.
2) If I was one of the survivors, there's no way I'm giving up the technology. You guys can go unplug if u want but I'm taking the toothpaste and soap with me. And a Raptor.
3) EVERY cyclon was on the colony when it blew? There's no other base ships with ones, fours and fives out there on patrol who are gonna come looking, or in 150,000 years are gonna stumble across the despised humans?
I still hold out hope that "The Plan" will offer up some kind of explanation that undermines the apparent god solution. We still may find out it was Daniel orchestrating things all along or something but I don't really believe that.
All in all it was a great series. In my mind I'll just re-write the ending how I see fit (another blog maybe).
