There is a saying in my country that something is a "shit in golden wrappings".
This is perfect example of that sentence,the gore,atmosphere,overall "creepyness" are perfect,but "the meat" of this anime is just bad.
The sheer amount of stupidity of the characters is overwhelming and it goes way beyond your usual "dumb teenagers in a horror movie".
The next issue is the pacing of the anime,its WAY too rushed,i havent played the game and for most of the time i had no idea what was happening and how and why.
If you like gore you can give this a watch but tbh just save your time and watch When They Cry,its way better.
