Same, I was immediately hooked. I don't think there's anyone who could've done that role as well as Tatiana Maslany. There is apparently also a spinoff that came out this year called Orphan Black: Echoes, set in the future and starring Krysten Ritter as a adult Kira I think? But I haven't watched it

Honorable mentions to Pretty Little Liars, Hotel Del Luna, Fruits Basket, Pushing Daisies, Veronica Mars, Yowamushi Pedal, and Dirk Gently
