I did a take on the best horror films on Netflix but this is just my favorite horror films and there will be some overlap.
This is either the second or first Slasher film depending on whether or not you count the Texas Chainsaw Massacre as a true slasher film or a proto-slasher film. However Slashers this movie inspired seemed to take the wrong message from it and as such it holds up really well. The gore and body-count is minimal, the acting is very good, and the story is well told. All adding up to one hell of a suspenseful and terrifying film.
This is one of those films that is perfect. The right mix of story, adventure, horror, and genuine emotion. I LOVE this movie. Good Job Mr.Spielberg.
The Thing (1982)
This to me is the ultimate exercise in paranoia. The film still has people wondering what the thing really is and what the ending really means. (My thoughts the thing is a demon from space, and Childs is a thing and Macready knows and is getting ready to kill him)
This home invasion slasher was filmed for 70,000 dollars yet is one of the best horror films ever made. It is well and truly a great movie.
Now I'm going to go re-watch Jaws if you don't mind
