I remember hearing about IT from other kids, and them describing all these horrific things that happen. When I watched it as an adult I couldn’t believe how tame it was. Everything had been exaggerated, and some of it was probably being confused with things from other movies.
Jaws was absolutely the first thing I thought of. So many kids suddenly developed a fear of ponds, lakes, and swimming pools because no one stopped and asked themselves if it was a good idea for a small child to watch people get eaten alive.
