What's your favourite horror movie?

There is a sleeper horror film that not many people know about called 'The Other'. Its very old from the 1970s based on a book by Thomas Tryon about 2 brothers. Its a very good movie, a more classic older style of movie of that era. If you havent seen it dont have any spoilers watch it cold, and you will enojy it. It has some truly horrible moments in it. A true 'horror' movie. Not like 'saw' or friday the 13th scary. Not like 'the excocist' or 'the ring'. a different older and truly creepy and memorable kind of scary.
