Spoiler
This movie does the #1 cardnel sin in the mystery suspense genre. It was all in there head the whole time! Than ontop of that!!! They have the audacity to do a flashsback sequence, the classic trope of "the hints where there all along, you could of figured it out if you payed more attention"
The movie was honestly kinda funny how bad it was. All the murders were so dumb and random it made me laugh, and the ending is one of the worst I've ever seen.
