Comparison between 2 thrillers (of the same sub-genre)

The sub-genre I have chosen for my comparison is the psychological thriller, and the two films that I am comparing are Psycho and Panic Room.
In Psycho, the theme tune creates a dark and unsettling mood for the first scene of the film, as the music plays at hugely different pitches to create this mood, whereas in Panic Room, the music appears to have several bars of notes that start off with a low note and then the notes gradually increase in pitch; so the theme tunes both create the same unsettling mood, but with different pitches of notes.
In Psycho, the entire film is in black/white, which works well with the thriller because it adds a sinister tone to the film, whereas in Panic Room, the colours are normal but they are dark and this is because natural lighting has been used in the film to portray the peculiar psychological aspects of the thriller.
In Psycho and Panic Room, a lot of jump cuts are used to work with the fast pace of the films so that the actions that take place happen quickly and can surprise the audience; which is obviously typical of a thriller.
In Psycho, the characters wear old-fashioned clothes and there is a scene where there is a woman writing using a quill, which clearly suggests that the film is set in the early 20th century, whereas in Panic Room, the characters wear fancy clothes (such as sparkly dresses and black/white suits) which you would expect people from the late 20th/early 21st century to wear, so the objects and clothes that can be seen in the two films clearly suggest what time period the films are set in, and it makes sense that they are presented so differently because Psycho was produced in 1960, and Panic Room was produced in 2002.
