The Others
Second viewing, the film is still just as good.
It really has a special atmosphere, despite its seemingly slow and uninteresting appearance. It watches itself, and you still find yourself captivated by what's happening, especially when you see it for the first time. Throughout the film, you try to understand what is really going on, and it is impossible to guess before the end.
It is clearly an unpredictable film, with an incredible twist that makes it unforgettable...
When you watch it again, you notice the clues scattered throughout the film that you missed the first time around.
