In the late 1990s and early 2000s "minimalism" was "in." It was sparked maybe by Don Davis' film scores for The Matrix which were stylistically postmodern and minimalist. A lot of composers got in the act with a sort of "all I have to do is add some repeat signs?!!" bravado.
Here is a film score by a prominent composer who used this sound specifically to portray a scary situation set in the future. Winner, if interested, gets a copy of the program from the NY Premiere of Violin Concerto No.2 at Carnegie Hall.
