Huge Gaps in Scenario but ok to watch - Spoilers

>Suffocation would have been diagnosed in a possible necropsy of Davids wife, this whole movie has no reason to 'be'. Suicides DO get necropsy.
>The girl gives out spoiler answers in the first talks of Charley connecting them to her father f.ex. David: Who opened the window Emily: I thought YOU did.
>I understand that the movie needed to disorient us because otherwise it would be so obvious that David is Charlie but they kinda abused it for me.
>After the cat incident we realize that Charlie has to be a physical entity and the cat was there behind him while in the bathroom. There where only two people that could have done that, Emily or David and no way the neighbor since the message was so personal the neighbor wouldn't have written it. Then looking at Emily's drawings Charlie is clearly a male figure leaving David as the only option.
>It was strange that Elisabeth and the Sheriff could enter the house just like that...Sheriff had the keys (!) and Elisabeth just opened the front door from outside (?).

I have to note that the screen of the image was excellent as was the sound where the audience could listen to all the little details at the environment, I really enjoyed that. The scenario needed more work though.
