This is one of the better apocalyptic dramas out there. This heart-in-your-throat horror drama full of blood, gore and action delivers in strong performances by a talented ensemble of actors and strong writing. Think the cast of LOST meets #Alive.

Although the topic of humans turning into creatures/zombies has already been explored, this one is different, though the details of how this comes about is as murky as the bowels of the apartment complex, where much of the action takes place. What is not lost on the viewer, however, is the metaphor of humans treating each other like monsters when hurting each other due to hatred, envy, or a lack of empathy, and literally becoming the creatures of their deepest desires who feel the need to kill or save humans.

What I love the most about this drama are the strong female leads. No Mary Janes here. The women in this show young and old, kick butt. Not only are they caregivers, teachers, grocers, musicians, first responders, and moms, they are also extraordinarily fierce when pushed to the brink of danger. See Yi Kyung, played by the beautiful Lee Shi Young, could have easily been played by a man. The fact that they chose a female hero is a plus. She is strong, smart, and protective of the tenants in the apartment building. The audience is provided with backstories through flashbacks of the main characters to better understand their weaknesses, and how they overcome them through the ensuing action. Some strategically placed comedic elements serve to break up the tension when the drama becomes too intense to handle.

Now for the bad parts: It's over-the-top violent and gory. There is so much blood, body parts and dead people that I felt caught in a violent video game. If you can't stand blood and guts, this is not the show for you. Some story details were ambiguous. It's not exactly clear why humans are becoming the way they are. There are some clues that are not explained which leads me to believe there may be a second season, else these nuances would be considered plot holes. The cliffhanger ending? There has to be a second season or it would be the most ambiguous part of the drama after all that suffering.

Would I watch this again? Yes! I need to go back and catch the little things I missed due to the break-neck pace of the story. It is very thought-provoking drama because it makes you ponder the human psyche. The black on white line drawing of the eye at the opening credits along with the classical music is a stroke of genius. It draws you in and slams the door behind you,
