The Maze Runner

Having finished this book I'm left wondering what the hell did I just read? This book was awful! The characters were flat and there were inconsistencies in the plot line. I still don't understand why the damn maze was created or who made it and that's the only reason I pushed through and finished this book. I kept hoping the book would get better, but it never does! How is this a best seller? The writing style was beyond simplistic and the dialogue just sucked. Ok it was interesting to hear some new slang, I give the author points for that bit of creativity, but really....how did this get published?
