Orphan Black rarely disappoints yet every season I find myself asking, how are they going to keep this up? When will the details of the experiment become too complicated and/or preposterous? But creators Graeme Manson and John Fawcett consistently delivered smart, fascinating twists and turns all throughout the first three seasons, and it looks as though the trend will continue in Season 4: the first three episodes are wildly entertaining and enrich the scenario and characters tenfold.

At the end of Season 3, most of the CASTOR clones were dead, Rachel (Tatiana Maslany) reunited with Susan Duncan (Rosemary Dunsmore), and Sarah (Maslany) and Kira (Skyler Wexler) decided to lay low in Iceland. When we reunite with Clone Club in “The Collapse of Nature,” their cozy hideaway is compromised and they’re forced to hit the road again. When they make it back home, Sarah starts investigating an especially mortifying piece of implanting technology that could have come straight out of a horror movie. As a diehard fan of the genre, I got a kick out of the biotech’s capabilities and the resulting creepy imagery, but the implants are also key to bringing all of the characters together while adding a significant amount of depth to the series.
