What are the best horror/ thriller movies? (scariest)?

Here are some great horror movies that I love and every horror movie buff should see. Jeepers Creepers, The Strangers, Vacancy, Silent Hill, Black Christmas, Quarantine, The Crazies, Amityville Horror, Dawn Of The Dead, Evil Dead, Night of the Living Dead, The Shining, Wrong Turn, Halloween, Final Destination 1 & 3, Mirrors, A Nightmare On Elm Street, 30 Days of Night, The Cell, Session 9, House of 1000 Corpses, Battle Royale, Drag Me to Hell, The Uninvited, Martyrs, Let the Right One In, 28 Days Later, Inside, REC, Midnight Meat Train, The Descent, Friday The 13th and The Last House On The Left. My favorite movie is The Strangers because it's actually scary and it's based off true events. It's also something different in the horror genre which I love. Liv Tyler did an amazing job in this movie and it will scare you especially if you watch it by yourself at night. This movie was well written and the director knew what to do in order to scare you and it's a very suspenseful horror movie unlike any other. The Strangers is a great psychological horror and is scary unlike a lot of horror movies of today. I also just bought A Nightmare on Elm Street(2010) which just came out on DVD last Tuesday and the movie is really good and it's creepy. Freddy is more serious and a true psychopath unlike all the sequels to the 1984 original where he was just a silly clown he is actually scary in this movie. It's worth your time and you should check it out. Happy Halloween!
