This is a fantastic movie with exceptional cinematography and stunning music selections...but its going to require you to pay attention, think and use your feelings. Imagery in this movie is everything. Metaphors abound. If you're looking for flash and glitz and pew pew pew and zoom zoomie cars, this won't be your movie. But if you don't mind a deep cultural dive and maybe a little homework to learn what's going on, this will be very much worth your time.
If you watch this movie and think nothing is happening you aren't paying close attention. Or nowhere near close enough attention.
It's subtle, there is the significance of the element of water, spirits and possession...possession of possessions, various fears from not knowing what's going on, bad dreams, are you dreaming or are you awake, after effects of violence, something getting inside you and taking over...so much happens!! There are more levels to horror than a maniac randomly killing random people having premarital sex and the gore of rubber intestines falling with a splat to the floor. A big modern social commentary that will slap you in the face if you're willing to listen...and that's more horrific.
