Im not crazy about horror movies, I find them to be borderline silly, although when I was a kid nightmare on elm street seemed scary, but when I watched it a few years ago, just silly...
I like the series american horror on FX, I believe you can buy series 1 and series 2 is almost over...
some that stick out to me are
Ju-on {I find Asians scary in general, especially when behind the wheel, jk
},
Salems Lot {something about them vampires stayed with me when I was younger, my neighbor had a dog that looked like one}
speaking of dogs CUJO is worth a watch, not super scary, but its ok
REC {quarantine was the american version/remake what ever you want to call it but Rec is better}
In the mouth of madness {I always forget about this one, but it mad me jump like 3 times the first time I watched it, that has to be worth something}
and People under the stairs is also a good watch, nothing that will give you nightmares but its watchable...
good luck,
