Harry Potter and the Goblet of Fire

So long and boring.
More than ever, Harry cannot do anything by himself, even when people give him major hints.

It is a shame that some mysterious elements are given at the very beginning of the book, and get suddenly answered in the “answers chapter” where everything is explained in an unending tirade.
As a reader, you do not have enough information to figure things out. You are just like Harry, going on and hoping things get explained at some point. Meanwhile, enjoy you childlish arguments and senseless elf-rights strife.
This book should be much shorter.

Additionally, there are many things that don't make sense : Truth serums not used in life-and-death trials, foreign students and directors spending MONTHS in Hogwarths doing nothing are only examples.
