The first 3 books were ok but not really dark, more cheery. The 4th wasn't dark but it was alot more exciting. The 5th was a great piece of work but it was so depressing. The headmaster in that book was a friggin bitch. I hope to see somebody like Ron or Hagrid killed in the 6th one. Twill add alot to the story. Its not that I don't like em, its just that somebody close should go.
