Knowing how much Junji Ito poured life and passion into his manga makes this show so disappointing.
Suspensful moments and shocks that come after a turn page are replaced with simple cuts. Some things are also very simplified. They seem to have missed a lot of what made the manga so great.
While yes, it can be seen as a very faithful adaptation the problems begin there.
Moments that unerve in the manga fall flat in the animation. Anything this show does is done infinitely better in the original. The way characters are drawn and animated are sometimes very stiff and if you look close then there you can see alot of mistakes.
There are alot of other mistakes but there is not enough room to list them all.
Instead of wasting your time with this, read Junji Ito's original manga. It's so much better.
