The Perks of Being a Wallflower

hm. I think I'll be the odd one out here. I have many thoughts about this book, some of them being:
1. how unusual and absurd, socially speaking, is it that a teenager in 1991 discusses openly things such as the erotic dream he had with the girl he just met? is he or is he not autistic?
2. if he is, why not use the behavior as something that may be construed as not just as idiotic? it doesn't do the autistic so wide spectrum any justice or favors that he is just naive bordering idiot.
3. has anyone counted the number of times this guy cries (hard) ? omg. seriously. gets old.
4. if he is such a genius, as Bill stated, one of the most gifted people blah blah, couldn't he at least every now and then dazzle us with more complex descriptions of feelings than the aforementioned crying hard or the very first grader sentences? I don't expect the use of corpulent or jaundice, dear, but make an effort!

Let me make it clear. Charlie is very sweet. Some sentences are almost poetic and the characters seem really interesting. But I do believe that after Holden Caufield, one must be extra cautious in creating American teenagers amidst some drama, especially if one is not going to really exploit any of it. All in all, if I had read this book with zero expectations, I might have found all the shallowness and idiocy endearing and maybe believed it was on purpose; but it was not the case, and I finished thinking that if I had been the editor... which is always a bad path, as you can imagine.
