Not recommend for manga readers

This is far so wrong compare to the original manga. I really hate how they destroyed it. The whole plot was different, the monster and the ending don't make any sense. I was so hype when hear about this adaption but ended up disappointed and felt like I was watching a random horror movie without any relations to the manga itself. If you haven't read the manga, this would be nice to watch (since the ost from Ado and the casts are good) but if you have, erase your memory and turn off your brain before watching.
