Orphan Black review: Tatiana Maslany leads the series to an exciting conclusion

Sestras, unite: After four seasons of dance parties, twerking, and who knows how many clones, the end of Orphan Black is almost upon us, as Sarah, Alison, Cosima, and Helena (all played by Tatiana Maslany, of course) inch closer to finally getting to the bottom of the conspiracy surrounding their creation. In the fifth and final season, the clones face challenges new and old, including one that is a little bit of both: The man behind it all — the 170-year-old Neolution founder P.T. Westmorland (talked about but not yet seen).

Despite answers to the show’s greatest mysteries seemingly on the horizon, Orphan Black has always been most interesting and engaging when it comes to the bond between the sister clones. That continues here, even as the stakes increase and the sestras are more separated than ever. “I’m part of a sisterhood that you couldn’t even begin to understand,” declares Alison in an early episode. Considering the science is as confusing as ever, we may not understand it, but we enjoy the hell out of it.

Credit goes almost entirely to Maslany, who after four seasons and an Emmy win, still continues to electrify any time she’s onscreen. Whether it’s as Sarah impersonating Rachel or donning the sheep mask as M.K., Maslany finds a way to make each of the 11 clones she’s played on the series its own dynamic and unique character.

If Maslany’s performance — combined with laughs, deaths, reunions, and pregnant Helena kicking ass — is any indication, the end of Orphan Black promises to thrill with an exciting conclusion.

Orphan Black premieres Saturday at 10 p.m. ET on BBC America.
