the grudge be a remake of shimizu own series of popular japanese horror film . shimizu know he be not deal with anything new and so he do what any intelligent person would have do in his place represent he forget logic and concentrate in give viewer a fun ride . he use commonly know clichés associate with ghost story but shimizu play with these element in an imaginative manner . the nonlinear narrative be not a mere gimmick but an interesting way to present sequence from different perspective . at the end and all i can say be that if the only purpose of a horror film be to scare the audience ( the same way a comedy be to make people laugh ) and this movie succeed with fly color . i watch it in a theater with an audience and it be fun to see viewer go wild over this one . it probably doesn not play as well in your living room .
