I'm not sure if it's horror but check out stake land
I liked stakeland, not well known actors but they did a good job, even tho it was another vampire hunter movie.
I've also seen and recommend "the woman in black" pretty decent movie, had me jump a few times just because of the "outta nowhere scenes" different ending caught me by surprise.
another few was:
-The Innkeepers (2011) - eh. decent scary movie to watch if nothing else on, wasn't great, wasn't badd.
-Intruders (2011) - turned it off halfway just because it was so slow going.
-The Devil Inside (2012) - another attempt at an exorcism, but a fail. seems like ever since I saw the original exorcist, all other exorcism movies doesn't come close, not even a little bit.
-The Rite (2011) - same as The Devil Inside.
-Underworld: Awakening (2012) - IMO they fukked this whole series up, I mean the other ones weren't great. but Awakening straight up sucked.
-Apartment 143 (2012) - meh, they tried, another demonic possesion move that had some jumpy scenes, the daughter was kinda hott. that's about it. lol
-The Woman (2011) - weird ass movie, had me watching to see what happened through the whole movie, decent movie if ur bored.
-Cassadaga (2011) - looking at the movie poster I thought this shyt was gonna redeem the Horror genre...I was wrong, decent movie to watch again if your bored, but meh. here's the movie poster:
