Every Battlestar Galactica Series And Movies Ranked Worst To Best
8. The Plan
The Plan serves as something of an epilogue to the series as a whole in terms of release order, but is actually set alongside Seasons 1, 2 and the pilot Mini-Series. It shows in truly glorious visual detail the bombardment of the Twelve Colonies, it fills in a lot of blanks about the logistics of how and where the Cylons were during the first Exodus and it focuses on the deliciously evil Brother Cavil.
It can't be viewed before 'Sometimes a Great Notion' in Season 5, since it is flagrant about the identity of the Final Five Cylons and would serve as a spoiler. While it's intentions were good, there were a few problems with it, it's plot is basically a fill-in-the-gaps story making it lack it's own agency, but the intentions are decent.
Not essential viewing for the overall narrative, but a great addition in terms of reflection and going back to where it all started.
