My favorite horror spectacle. I first saw IT when I was 7 or so, and absolutely fell in love. Never before had I seen a horror film that was so... well, horrifying! Most horror is based on blood, guts and gore, but IT is something truly special. It harnesses the psychological aspect, and makes you fear, not only being brutally murdered by a potentially pedophile clown, but also to fear looking in the mirror at your reflection. It makes you think twice about opening your eyes when you hear a noise in the dark.
Pennywise, one of the most gruesome and terrifying characters ever dreamed up, uses terror as a weapon, and feeds off of the fear of his victims. This is a beautiful concept, when compared to an average horror film, which mainly uses jump scares and large knives to induce fear in its characters and viewers. IT the film adaptation has quite a few bits about it that are unmistakably different from the book, but that, for me at least, did not make the film any less enjoyable. I truly love this side of King, where it's a fear of the unnatural and the ambiguity of the mere concept of terror. If you haven't read the massive book, and enjoyed the film, I do highly recommend dedicating a solid chunk of your life to reading it. No other film is quite like IT.
