I have a fair share to put in myself, really...
First off-and you all can stone me to death with this one-but the biggest by far is The Great Gatsby. The only thing great about it is its effectiveness in curing insomnia.
Second on the list is Catcher in the Rye. Just one big, long "angsty" teen bitchfest.
You all know my opinion on Shakespeare.
And perhaps a toss up in the air, Lord of the Flies. Not really my cup of tea, especially back when I first read it as a child.
