HunchBluntley: The Others was a really good old-fashioned supernatural thriller. I think it has a couple of what could be considered jump scares, but mostly it's just a mysterious and tense build-up until the end.
That one is one the few that actually surprised me and also didn't told me everything about the movie in 10 minutes.
Freaks Of Nature (2015): More funny than "horror" really.
Devil: 5 people in an elevator - who's the devil? (highly recommended!)
Ghostship As above so below Trollhunter Below (2002) Deliver Us from Evil (2014) Dolls (1987),
Bad Taste (1987),

The Gate
Insidious 1-3 Apollo 18 (2011),
Europa Report (2013),

The Mangler, Trucks (Maximum Overdrive?),
Christine: Steven King
The ABC's of Death 1 and 2: Directors from every corner of the world are given one letter of the alphabet to make a word and a short movie about it. Some hit and miss, but some of them are quite good actually. Some are rather nasty also.
Constantine Pan's Labyrinth and Coraline: Not exactly horror, but very dark and creepy.
The Phantom of the Opera "Abrupt change in image/sound/music"? That's like describing most movies since 1930's :-)
EDIT:
The Wraith (1986)
There's also one that I can't remember - it was an old car, black, that terrorized the roads. It's not the Car (1977) I think...
