Probably the story line was short and should have been portrayed in a way that filled the right time. Ah, I said the right time. Why should it be over two and a half hours? It could have been an hour and a half. The director must have his reason. However, the story line was so scary that at the end of the movie, I just wanted a happy ending. I know that making a film with stories like this requires various issues, but if I were the director, I would definitely shorten the time of the film. Three relatively similar narratives with minor changes only waste the audience's time and reduce the excitement of the audience. However, you should also listen to the director's reasons.
