Five Nights at Freddy's is a horror film based on a video game. The movie is likely to creep some people out since the creatures in this film are very large animatronic bears similar to what we saw as children in places like Chuck E Cheese.
Mark and Ryan are somewhat split on their rating giving it a 6 and 7.5, respectively. However, they both recommend seeing it if seems like something you're interested in.
The film is rated PG13 and some young audiences may find it scary. Most adults are unlikely to think it is very scary but there are certainly some very creep scenes.
