The plot is horribly executed and forced, the characters are just awful. I am a horrible fiction writer and i am certain that my six year old sister or myself can write a better story.
Now i'm going to tell you the main thing that really upset me with this show. What happened was that throughout the show you hear the main character making promises about protecting everyone and then doing a piss poor job of it. or even better, she just won't do it. Will wait until every last person she's trying to protect is dead before being able to spring into action.
The only thing that's keeping my attention are the gore scenes this show has to offer.
My advice, you will hate this show. And anyone who says its really good is lying to you.
