This movie makes no sense

Rating: 6/10 (15 September 2019)

A mentally disabled man who himself was kidnapped as a young child 26 years earlier kidnaps two young girls in his RV and brings them to his aunts house where they are forced to do mazes. The aunt has dead snakes buried in her property. Five years prior, the aunt's husband is murdered by a priest after the man confesses to the priest that he killed 16 children. At the same time, there is another man with a striking resemblance to the mentally disabled man who breaks into the kidnapped girls' homes, steals their clothes, covers them in pigs blood, and locks them in boxes with snakes. This man has an obsession with mazes and is clearly connected to the other villains.
It is never explained how the maze-and-snake obsessed man is connected to the aunt and her nephew, but they are obviously connected. It is never explained why these people were so obsessed with mazes and snakes and it was never explained why they needed to kidnap young girls to use them to solve mazes from a book.
Clearly the main characters in search of the missing children are just as confused as the viewers given there is no meaningful dialogue among them. They just scream, run, beat up people, and cry. The main characters essentially are just used to clue the audience in very slowly about the absurd and obscure plot described above.
So yeah, this movie doesn't make sense. It could have been a better movie if they explained the meaning of the mazes and snakes and gave more insight into the connection between the aunt, the mentally disabled man, and the man who steals the children's clothes.
