If you want to get into screenwriting, The Grudge is worth a watch because it’s a masterclass in what not to do. It shits out exposition around every corner to skip past parts of the story and give 5 second character backgrounds, giving the film a hilarious, brain-rot pacing.
It proves proper build up, atmosphere and characters are needed to make a horror film scary, because none of that is on display here. All the film wants is to show off a creepy dead girl climbing out of a shit-filled bathtub; perhaps a metaphor for how much of a shart this film is.
