No reason to watch it in 21st century

Rating: 3/10 (2 October 2017)

Well, first thing first - my rate to this move was 3. I did rate it 1 in the evening after I saw it, but reconsidered that in the morning.
This is spoiler free review.
The move has a good idea, which has enough matter within it to be enough for about 4-5 minute clip. Nothing more. This movie is 2 hours of pure torture to one's senses. Each scene was carefully crafted to drill in your mind and torment your soul. There is nothing to be comprehended from most scenes anyway, nothing that can't be laid out within 30 seconds. The sounds are going from 0 straight to 80 decibels in a second and then back and then forth and then back... I had trouble sleeping after it, not because I was afraid of something but because I felt tormented.
Highly unnecessarily graphic, too 70s-arty and it feels like some bat sh*t crazy hippy on LSD spat it out from deep within his delusional intestate.
Would not recommend it to anyone, but perhaps a directing student, who is after "classics". I give it a rating of 3 stars because of the clever and teaching idea, which has nowhere close enough matter to hold meaningful focus for 2 hours.
