Why does everyone say Selena Gomez is so great in this? I am sure she is a very nice person and people want her to succeed and all that, but she is definitely the weakeat link. Monotone dialog, emotionless face. Unless they make her the killer in the end, which she is not, I can not honestly in good concious say she does a good job, she does not, and this has been obvious to me from the first episode. The actress playing Steve Martins daughter is a way better actress IMO.
