I don't believe in the world of this book, nor in its worldview.
three children and two teens, ages 10 - 17, trap a 20-year old babysitter; over the course of a week, she is repeatedly tortured and raped. in the end, they torture her to death.
5 kids are not going to quickly turn into psychopaths able to systematically abuse and murder a person within a week unless they were already deranged. only one of them is characterized as having mental issues; none have traumatic backgrounds or guidance from a disturbed adult. there is no believable context to why they do the things they do, unless it is mere coincidence that brings these 5 deeply disturbed individuals together. that's a hell of a coincidence. no, I don't believe in the world of this book.
on a formal level, the writing is excellent. really, quite top-notch. the perspectives of all six major characters are interestingly depicted. interestingly, not believably. surprisingly enough, the intellectual, clinical, yet oddly dreamlike manner in which Johnson views his subjects reminded me of writers like Duras or Ballard or film directors like von Trier or Fassbinder or Lynch. but you do not often approach those authors or directors as if they were depicting actual reality, real life there on the page or up on the screen, breathing and bleeding and genuine. instead their works have an almost ironic distance from the material that encourages contemplation of - rather than engulfment by - that material. one could try the same approach to this book. good luck! Let's Go Play is not an extended metaphor; it shows the actual thought processes involved during this situation, how escalated forms of projection and objectification and role-playing can lead to atrocity. the author brings a certain sardonic detachment to the material, but this is no stylized dream odyssey. it attempts realism but tries to paint human nature as inherently monstrous, psychopathic. that is not reality.
there are reasons given for the kids' actions. "It's all a game" ... "There always has to be winners and losers" ... "The world is all about hate" ... "We voted" ... that old bugaboo, violent media ... etc. the reasons provided are not convincing enough for me to believe that 5 kids (ok, let's not count the lil' psychopath) - 4 'regular' kids without traumatic lives or the guidance of a disturbed adult - are going to be able to slowly and dispassionately torture someone to death, and then methodically cover their tracks like supervillains. I call bullshit on that. I don't believe it. there needs to be context for such actions because all humans are not all monster. well, perhaps I am a glass half-full sorta guy after all.
