Suffered from Setup Syndrome to a certain extent, I can really tell the 3 parts were intended to be totally seamless.
Nonetheless, I've never been so captivated by setup in my life. I was surprised by the flashback's, and I really loved that stuff. BSG, even in at the end when the huge plot needs tying up, never abandons it's commitment to the characters and texture of the BSG universe.
This is gonna be a long ass week.
