In the Tall Grass does precisely what it says on the tin — something sinister and other-worldly lurks in the tall grass. Ditching the foggy and raining comfort zone of Maine, father-son duo Stephen King and Joe Hill came up with this set somewhere in mid-west America.
Together what they have created is a monster that steals the show rather than the characters. The field of the tall grass itself is a bigger mysterious entity that plays on people's psyche to trick them into walking into itself.
The grass then creates a maze, eventually trapping and killing its victim. Then, it entraps other people by reanimating the souls of those who have been lost to it.
The movie is a slow burn, but true to the genre and the writers’ prowess, it ends with a bang.
