Gave it an Above Average.
They should've called it "A Tale of Two Cavils"
It did feel a bit clipshowy, but then again maybe that would be less unwelcome had I not recently rewatched the first three seasons. It's all very fresh in my mind.
I think it did a good enough job of tying in the cylon half, though I think I would've preferred had they gone back farther before the fall. The actual insertion of the final five into the colonies would've been welcome. Also I'm surprised that they went with the "it's all happenstance" route with the final five surviving the initial attack and ending up on Galactica.
