looking for thrillers

the more unhinged, the better. prefer if there's supernatural, but simply a crime thriller will do too. 

please don't recommend any with melodrama subplots. i don't care how subtle it is, i don't care how good is the plot otherwise, if it has romance then i don't want it.

examples of what i'm looking for: adamas, the guest, the wailing
examples of what i want to avoid: awaken

thank you :)
