“In the Tall Grass” is a Netflix film adapted from a short story/novella by Stephen King and his son Joe Hill. To be upfront, I haven’t read the original story, so I can't comment on how closely this movie follows it; instead, I'll evaluate the film itself, and there aren’t many positive things to say. The story begins with two siblings, Cal and Becky, who is pregnant, as they drive through Kansas—a welcome change from the usual Maine setting for a Stephen King story. They stop when Becky experiences morning sickness, and hear a boy calling out for help from within a field of tall grass. Soon, they become separated and realize something strange is happening: moving in one direction doesn't guarantee you’re going that way, and time seems distorted. Along the way, they encounter others in the field, including Ross (played by Patrick Wilson), his son Tobin, his wife Natalie, and Lisa’s ex-boyfriend Travis. I had to look up the names of these characters because they didn't make much of an impression on me—with the possible exception of the boy, who comes across as unsettling from the start. It wasn't that I wanted any of them to die because they were annoying; rather, they’re so generic and stereotypical that they don’t leave a lasting mark. Part of the reason for this is that the audience can get too preoccupied with the grass itself. While it does possess a certain atmosphere, it’s difficult to understand how it functions. I found myself distracted trying to figure out the grass, its workings, and what it was meant to convey, which took away from the human characters. This brings up another issue. Because most of the setting looks identical—a field of tall grass—the filmmakers have to rely on various technical and visual tricks to keep viewers engaged. However, these are inconsistent and noticeable when they appear (for example, a recurring shot that’s a 360-degree rotation). They feel artificial; you notice the trick instead of what it's intended to show, although the filmmakers seem proud of some of these effects. As with many horror films, there are jump scares, but those essentially constitute all this movie has to offer. The ending is fairly unremarkable and doesn’t really align with other aspects of the plot. Overall, if you’re a dedicated fan of Stephen King or Joe Hill and have nothing else to watch, it might be worth checking out, but for most viewers I'd suggest skipping it.
