The bad:
The mystery was not something new to me, so it was not so schocking.
Its view on psychiatry and pharmacology was extremist, saying how it was no different from radical experiments or surgeries.
It seemed, as I read some other reviewer say, as if the author wrote it thinking of a screenplay, rather than just a novel. Although that's not bad in some aspects, in others it just gave it an unrealistic touch.
The good:
It was one of those unputdownable books.
There were still some mysteries I hadn't guessed.
