When I first started watching this film, I didn't have very high expectations for it. However, when I proceeded to watch it, I saw what all the fuss was about.
The Shining is a movie that I think is perfect on every scene. It was shot in a beautiful environment which laid a nice atmosphere and made it rather unpredictable on what was going to happen later in the movie (no spoilers).
The movie gradually got better and better, eventually getting to the point where it couldn't exceed the level of greatness it was at.
Although this movie was made 3 decades ago, I still believe that it's one of the most terrifying movies to date, period.
This movie certainly crawls its way into my top 5 movies list.
