This show is awesome, I never get tired of the suspense and I think they really keep viewers on their toes! I think the story line and the acting is great, I just don't understand why people think its so terrible.
I cant take my eyes off the screen when I watch this show.
I dont think the story keeps repeating, the whole point is trying to find out who killed their friend. They keep thinking that they have the answer but it turns out they are just wrong and have to keep looking, I don't see that as repeating the story.
