ok so i thought this was the abyss but i watched it tonight and i guess i was way wrong. in said movie (80's movie) where people discover aliens (under water i thought) and the aliens like tell the humans to be good or else and they threaten them with this big wall of water from the ocean and the water is just like sitting there and everyone's like on the beach looking at it and stuff. i kinda have to know what this movie is. was i dreaming? am i crazy? someone help please
