Some movies end when the credits roll; others are never truly over and haunt the viewers back into the ordinary rhythms of everyday life. If there is one genre that is particularly adept at leaving a lasting impression, it is Horror. Whether it is the eerie atmosphere depicted, the visceral cruelty of the plot, or the disturbing themes explored, the best horror movies of all time often go beyond scaring the individual for a moment — they stay with them for a long time.
