Well worth a watch, not a traditional horror movie. It has Stephen King's signature style all over it. The disconnect for most people it seems is that, the movie operates on a non linear or traditional sense of time travel. The whole movie has paradoxical time jumps, which if you follow the trail don't make sense but this was almost certainly the point of the movie. The movie actually manages to give you the feeling of confusion and fear and just overall being disturbed by what lives within the grass. Go watch it for yourself! Definitely a mindf*ck
