Guillermo del Toro’s FX series The Strain is one of the creepiest and most entertaining shows we’ve seen in a while, made all the better by the fact that Mia Maestro appears as one of the leads. She plays Dr. Nora Martinez, a CDC scientist trying to save the world from, well, a strain. But there’s more to it than that. I won’t spoil it, but if you aren’t watching it, you should. Just be warned: the violence can get quite gory, so it definitely isn’t for young children.
