I didn't find Allie Fox likable, charming, charismatic, or engaging. I hated him. He was a tyrant, completely insane, and dangerous. His favorite past time seemed to be mental mind ****ing others, especially his own children. I even disliked the mother for allowing such a dangerous man with such a loose grip on reality to remain at the helm of their family for so long. Even towards the end when Allie became psychotically dangerous the mother seemed completely incompetent to step up to the plate and take control.
He was an ego maniac, a terrorist, a torturer, a liar, a control freak, an abuser, obsessive compulsive, paranoid, and self centered.
This was not some genius with charming eccentricities. The guy was bat**** insane and behaved in alarming and menacing ways. While the mother sat by doing nothing the kids were held hostage by an insane person.
By the end of the book the only character I felt close to was Jerry. He was the only one who clearly saw the dad for the monster that he was.
