You're welcome. I have seen the 1998 and 2009 versions wasn't all that impressed. The 1974 film is the closest to the novel. Plus people don't realize that the story was written during a time when New York was in urban collapse and the city started to become more liberal and more crime ridden.
We as a country had no idea how to deal with foreign and domestic terrorism. Therefore the 1974 film is ten times more scarier in my opinion.
