I enjoyed the remake, but felt the original Swedish version was a little better.

Perhaps give Dream House a try, not exactly a horror film and nth to write home about but it was ok.

I don't get what everyone found so scary about The Grudge (both the original and he remake), they got pretty predictable early on and I thought the jump scares were overused to the point it felt cheap.

Bronies and Bieber's movie count?

:-P

Event Horizon at 2am worked for me.

The Ring did not.

Actually, I think both the original and the remake have their points: they're different pictures, but the Matt Reeves version is smart and graceful. I prefer the art-house feel of the original, but Reeves made some very subtle shifts in the story that I enjoyed seeing; and the original, with its bum-translation subtitles on the first DVD release, was a problematic film after it left theaters.

Much as I love both of them, however, they are not in the least scary.

Was surprised it took 3 pages until someone mentioned this.
Though not a recent horror film, The Thing has my vote. The scarriest creature I've ever seen in a film to date; and the fact that there's no cgi makes it even more frightening in terms of realism.

Scary, no
Thought provoking, Yes :-)

never thought the thing was scary
impressive ? yes
awesome ? yes

scary ?
not so much

the orginal is better if you want paranoid scares

speaking of paranoia
bodysnatchers 1978 is pretty good

I leave "let the right one in" for another time, as I expect a real classic movie with that one (i almost saw it at a festival, years ago, but the theater was full and i hadn't booked in advance - it then won all the prices, i was frustrated).

I also postpone my 10876th rewatch of "the thing", just to catch up with my rewatches of the other Carpenter movies (I have a soft spot for that guy). But hey, it reminds me that I have not seen any "Master of Horror" short movies : I still have the unwatched "Jenifer" (Argento) and "Cigarette Burns" (Carpenter) on dvd. Speaking of which, I have afew Argento ahead, but I do find him generally more artsy than scary.

I saw "Pandorum" and "insidious". I might check "the possession", as I assume you don't mean Zulawski's (a sweet movie, but already seen a couple of times).

Isn't "I spit on your grave" an adaptation of Vernon 'Vian' Sullivan ? Or is that something completely unrelated ?

Also, I must have seen all versions of "Body Snatcher" and their derivatives (like "puppet Masters"), as well as the terrifying "Don't look now", as we are mentionning Sutherland...

I liked the remake as well but a few of the changes were too on the nose for me in the but Matt Reeves definitely did a great job with the movie. The kids in the original movie though really make that movie, thankfully I saw the version with the theatrical subtitles as I was aware of the botched translation for the first DVD release. I certainly agree that neither of the movies are scary but they ask a lot of thought provoking questions that one wouldn't necessarily associate with these type of movies. :)

Heh. I am not a great fan of Zulawski's "Possession," actually, though I will watch it when it comes around. No, I meant the modern Dybbuk-box one, which had some good moments. (My favorite Zulawski is the much-maligned "Szamanka," which I loved despite the fact that half of the audience in my screening was giggling by the end.)

Be aware that "I Spit on Your Grave" is a controversial gang-rape/revenge picture. It is extremely polarizing. It was clearly made as pure crude sexploitation, though the producers argued post-facto that it was actually a movie about female empowerment. To their credit, there is some substance to the claims, but it's mostly a rape thing. Nothing wrong with seeing it, but I'd hate to think you were stumbling across it unawares. It was remade in around 2010, though I don't think anyone really bothered to see the remake.

Now that I know your tastes better, I'm going back to my recommendation of ILS: http://www.imdb.com/title/tt0465203/combined

'The malediction' is for you. Clean horror.

how about shadow of the vampire ?
anybody seen that ?

Manos: The hands of fate!

I highly recommend Kiyoshi Kurosawa's unique masterpieces of cerebral horror Cure & Kairo.

A few other Asian horror films I highly recommend watching:
A Tale of Two Sisters (Janghwa, Hongryeon)
Three (Saam gaang - released internationally as Three Extremes 2 although it's actually the first of the two anthology films). I really like the first segment called Memories but the second one The Wheel is utterly terrible and boring while the third Peter Chan's breathtaking Going Home is an absolute must-see.
Dorm (Dek hor)

Then there's...:
Don't Look Now
The Exorcist III
The Kingdom (Riget)
Vampyr
The Vanishing (Spoorloos)

Although I've left out any of the films you've seen as well as those others have already mentioned I simply must second the recommendation of Tomas Alfredson's sublime Let the Right One In (Låt den rätte komma in).
