Top 15 Water Based Horror Films

It was a conversation from Dai and her not liking aquatic films that prompted me to create this list just for her. As I gathered the most notable titles in this area, I began to realize that there were alot of water-based films that I really liked. In fact, I'll go as far to say as "favorites". Though there is a bit of difficulty when creating a purely aquatic list. That being the level of water use in the film. What capacity, was the horror "water" or what is in the water? All these little details that don't always align.
