I have totally, never in my life, written a review of a TV show online before but I felt moved to write something about this one. I binge watched this in one day. That's how engrossed it kept me. I could not turn the TV off until I got to the very end. The acting was believable, exactly what you would expect a family in that situation to behave like. The twists were unpredictable. I was so shocked when the killer was revealed because I had convinced myself it was at least three different people before I actually found out. The roller coaster of emotions I felt watching this, first feeling bad for the dead guy, then hating him. Hating the kidnapper, then empathizing with him. You just do not know how to feel about the characters until damn near the very end. I'm currently rewatching the entire series to see if there were any details I missed the first time around that could have clued the audience in to what would happen in the end. I have been thoroughly entertained by this series and a lil scared now too because this is the kinda stuff that actually happens in real life.
