"In the Tall Grass" went into the weeds
I'm a sucker for these Stephen King film adaptations, but as we know they are a mixed bag. This one is right at five years old and is streaming on Netflix. There seems to be a bit of a parallel with Children of the Corn, but the movie does introduce some new elements. The characters spend a lot of time wandering aimlessly through the grass which gets a bit fatiguing. Their disorientation becomes entirely predictable. There are two structures and a small clearing which provide some relief. The pregnant sister is in distress throughout the movie which is overused as well. The antagonist reveals himself posing as a benign character early in the film, but you are immediately skeptical (he tries to sell it way too hard). There is a child lost in the grass who lures the characters in but denies doing so. There is a time-travel element which is thrown in to amplify the confusion. The rules aren't clearly defined, and it seems to only make the consequences inconsequential. There is a whole army of masked bad guys running around in the field being assholes. This element isn't fully developed, just don't let them grab you, okay? There is a dog who seems to help the plot at one point, but it's another dead end. There are a lot of dead ends in this big open field.
TL;DR summary: skip it.
