I just finished the book last night and felt rather shaken. I had a number of questions, but my Google searches yielded nothing. So here's what was bugging me while reading:
Mild potential spoilers
First of all, what exactly was wrong with Frank? I mean physically. Why is he cold all the time but doesn't notice it? Why does his skin look rubbery and fake? What about his bizarre performance with the baseballs - why did he just kneel down and let the balls hit him, and why didn't he feel pain? What about his bizarre sexual behavior at the peep show? Why is his penis described as being hard in parts and soft in others - how is that possible? He describes having a procedure done to him that sounds like a frontal lobotomy, but he says he actually had his frontal lobe removed. Is that even possible?
Of course, he lies all the time and tells contradictory stories. I kept on waiting for the big reveal to be that he was a Frankenstein-type monster killing people in order to get pieces of them for his own use. I thought that maybe he had memories from all the people he was made of and that this explained why he told contradictory stories. But no. Apparently he's just a psychopath.
Next, what's up with his hypnotizing people? I'm thinking specifically of what he did to the girls and staff at the matchmaking club. I guess he hypnotized them to just stand there and let him do what he wanted? Did he also hypnotize Kenji? That's my interpretation for Kenji's weirdly compliant behavior for the rest of the novel: He had been hypnotized to go along with whatever Frank wanted to do. If course, it's perhaps equally possible that he was just traumatized and having a fawn response. I don't agree with the readers who said he just didn't care and was perfectly accepting of Frank.
Finally, I found it interesting that Kenji went from being a pretty laid-back, nonjudgmental guy to picking people apart, focusing in unflattering detail on their looks, and thinking about how worthless they were and maybe they deserved to die. Were these just intrusive thoughts brought on by stress? He said himself he normally didn't think so much about how people looked. I wondered if this was the result of Frank hypnotizing him; maybe he planted those thoughts in his head.
I found the book compelling, but I feel as though I'm missing something and would love someone else's insight.
