No nonsense horror you can get from:
1)Day of the dead
2)Evil Dead
3)The Thing
4)Hellraiser
5)The Omen
6)The Exorcist
7)Texas Chainsaw Massacre
8)Wrong Turn
9)Saw
10)Alien

When it comes to "Tingles down your spine" visuals and plot, you can't beat the classics.
Also the reason why I'm a horror movie fan.
