Man after what you said I guess you have a point you just can’t stand those scary movies where the only way to defeat the monsters hold on them to give it what it wants or who. To me, I gotta say that scene also reminds me of that familiar scene of the movie come play.

you know for this movie I actually thought it was like In the nighttime of the pool it opens a dark gateway to the deepest side of the water and in their lives One of some fish people that once the gate is open they swim up ahead to see what they can find and catch what interest Them or even what feeds them. Right here it just looks like a zombie/ghost story a little bit like poltergeist but underwater What can I say? I think my theory sounds better.
