Grave Encounters is good, haven't watched Strange Harvest or Bring Her Back yet, but the trailers looked promising. The really good ones are hard to find, since they've been banned in many places.

I thought Cabin in the Woods was a very smart horror movie with an unexpected ending.

Haunt

This one is a classic, and offers a few good laughs at the same time

Island of Terror

Or how about The Haunting

Phantasm part 2 and 3 are great. Skip part 1 its just too slow. There's a recap at the beginning of part 2

I enjoyed final destination Bloodlines

Longlegs was spooky

30 days of night

Hellraiser

Salems Lot

Gore gore girls 70s horror

😱

I always go with the classic Universal Studios Monsters, their psychological scares are far more thrilling than modern gorefests.
