I hate plot holes.
Like, in Sex and the City, why didn’t Big have a best man? Wouldn’t that have solved a LOT of problems? She has 3 bridesmaids and he’s on his own?
And in BSG, Series 2, when the “reporter” who turns out to be a cylon, comes aboard the Galactica, why don’t they insist that every civilian who gets onto Galactica is tested? Wouldn’t that be just a basic security measure?
