I just saw it. It was interesting but they jumped through a lot of hoops.
The Plan should have just been:
-To breed human/Cylon hybrid babies, born of 'love'
-Cavill also wants to find Earth
Neat, fits the majority of the series cleanly, Cylon attacks can be "increasing the pressure" to find Earth, etc etc. They just overcomplicated the whole thing.
Back in the 1st season I actually thought that's what it would be all about... Helo/not-yet-Athena... Boomer/Tyrol... Baltar/Six.... all human/Cylon pairings in which they attempt to create 'love', then a hybrid child. It seemed to fit.
