Firstly, it was pretty creepy reading it. Can't go wrong with a guy alone in a forest at night with abandoned buildings around him.
The script felt like I was reading two different stories. One was about the old lady, Miss Gretchen, and the other being about the statue and didn't know if or why they were connected. If there was a connection then that needs to be brought to light. Also, the rules of the statue and what it actually was didn't make sense. Why was the face covered in red paint? If Wilfred took the statue's place, why wasn't his face painted red? If the title says, "The Devil Knocks At Night", why was there only one scene where there's a creepy knock on the door? Emphasis was needed to more on the knocking as one of the rules of the statue. You could make the knock itself more ominous and distinct so that nobody would want to actually answer it. Then it would beg the question; what would happen if someone actually answered it? They could die or take the statue's place then maybe.
The story also was a little predictable. Try and implement a few jump-scares as he's venturing through the theme park. Even though he is recording the whole time, people have seen footage of sounds being heard and loud bangs but still don't believe it is real. This could also enforce his audience to ridicule him, even more, saying it's fake. Another way to make things unpredictable is to create better twists. Maybe a character isn't who he/she says they are or maybe the old lady didn't actually die.
I think you should've focused more on one of the stories and have into interwoven with both the past and present. If I had to choose, I would pick Miss Gretchen's story. Wilfred saw the ghost of Miss Gretchen in her window as his Mum was carrying him out of the house signifying that her story wasn't over. When it didn't come back, I felt like that was a missed opportunity. I thought the twist was that Miss Gretchen's spirit had possessed the statue and as this statue, she would've caused these six victims' death. I felt like that would've been a better ending. You could even add some history behind it. Maybe there were three statues altogether, the other two being "Albert" and "Alice". Who were these people? Can't know for sure so give them some meaning and purpose. If questions aren't answered, take it out.
Lastly, I think the dialogue could use some work. Try not to have lines that are too cheesy or again too predictable. If Wilfred is 26, he should talk like he's that age.
