AVClub: For all the mind-bending action, deepening conspiracies, and technological feats, Orphan Black is still at its heart about two things: the fights for families and for control. Both these themes do get some straightforward attention. The right to control has been explored in depth with the clones’ genetic sequences, kidnappings, captivity, and the pure power of knowledge. Then, the fight to protect their families drives the emotional beats. After all, the only reason Sarah took on Beth’s identity in the first place was because she saw it as the only chance to get enough money to run away with her daughter. As the series has progressed, though, these two struggles have overlapped and intertwined. Family and control have become inextricable from each other in ways that both sing and sink.
