Psycho

This movie was perfect, it was really, really good, the plot twist is great, the filmmacking technics are revolutionary, the script and storyteling is top noch but the best part was the way that this movie was able to keep the tension on that last hour of the movie, I was scared, the part when the sister goes into the house is scaring and I was thrilled, and I think that that is why the movie works so well, it builds tension, mystery and horror.
