Every episode of Flashpoint begins with an awkward situation which looks pretty clear cut, someone is doing something dangerous and the SRU is there to stop him/her. But the episode progresses are we learn the whole story, even sympathizing with the original "bad guy". This requires a degree of contrivance for the tables to be completely turned every time, but it's somewhat believable most of the time.
"Through A Glass Darkly," though, is so far out there that it's hard to take seriously. Two guys kidnap kidnap a girl, because... they tricked granny! That they would kidnap the girl--and her mother--in broad daylight is already suspect, and the stuff about fooling the grandmother was perhaps more bizarre and unbelievable.
Score: 7.8/10
