I dont know if many ppl know this...But this movie is based on a book by Paul Tremblay titled The cabin at the end of the world. Great book! Ppl should check it out. This movie is on peacock right now. Its not bad, not great. M night changed a few things from the book, including the ending. But i suggest checking it out. There are some ppl on here who are saying its a great horror movie, but its not a horror movie at all. More like drama/suspense. Not a high replay type of movie, but enjoyable never the less.
