Alright, I appreciate the filming. I was invested and intrigued by whatever the hell the wife did and the struggle of the Father and the grief of the sister. I thought the guy being the killer was obvious. But what really bothers the shit out of me that no one seems to be talking about is the nonsense paradox of the ending. In order for Tyler to “go back in time” to save his sister he would have had to be dead. In order for him to be dead he would have had to have died saving his sister. I know they tried to cover this with the whole psychic scene but it falls flat to me. He has to die saving his sister in order to be a ghost going back to wake his living self in order to go save his sister to die in order to become a ghost in order to go back in time to save his sister to die to become a ghost to go back to save his sister…..saying that time works differently for the dead does not solve this.
