Soooooooooooooooooo many questions... Zero answers

Rating: 6/10 (3 January 2019)

This movie may have been better if we knew what exactly they were ruining from...
Where did the entity come from?
When her sister saw "it" why wasn't she effected?
Were pregnant women immune?
Why do some want you to see it?
Why did it not attack them while they were on the river?
Is it afraid of water?
I have so many more questions.
