Yeah that's pretty much spot-on. They are getting better though. Kinda.
Oook... and given that this takes place... like 10-15 years in Japan's past (well more like 25 years given when it came out)... It is doubly true...
Still remember that scary scene where a woman, due to gambling problems caused by abuse she received at home, had her child burn to death when her car was on fire because she abandoned him in the car. So when this was found out... basically everyone in that business felt it was their job to punish this woman and not only harassed her but it was implied that just by working there she could actually lose them customers.
To admit while I say this... The main character actually sympathized with the mother because she experienced how inconsolable she was after it had happened, that she would cradle her dead child and even managed to cry tears of blood because of it and was willing to actually stick her neck out to for her... An act of love and tragedy so immense that it moved her so much that she took it upon herself to convince this mother to live and to atone by living a better life because suicide is too easy... The main character being the one who hired her in the first place and considered this woman to be the strongest person she ever met.
So basically yeah Japan can criticize Japan quite well at times.
So basically Screw the source material we want money.
The vast majority of humans aren't anal retentive about every adaptation being identical to the source material. You might want to look at that expectation from the outside.
It isn't that... It is more of a "Why bother?" situation. They want the recognition and some of the skeleton of the source material but none of the heart... While substituting their own material that no one would buy into otherwise into the now blank slots.
A typical Adaptation is you keep only what you need and discard the rest... removing even what was normally important elements if it was necessary... What you can't keep you can also translate and make it take a new form.
OR you take a piece and make it "Inspired" by the original, a sort of retelling where there are only meant to be similarities but is otherwise a completely different work.
It is kind of as they say: "If you wanted to tell your own story, then tell your own story. Don't take someone else's story and present as your own".
