Five Nights at Freddy's movie has an interesting parent child relationship. In the movie the brother is taking care of his younger sister in unique new paring. The brother assumes less dominion then the usual parent child relationship we see portrayed. Also the older brother also gets support from others to retain "custody" of his younger sister.
You might want to rent this movie later or just see it in the theater.
I usually don't watch scary movies because they don't scare me. This scary movie didn't but it has a nice story.
