Butting in here but GOF has two of the weakest things in the entire series, IMHO. #1 That "Moody" was surviving on Polyjuice for 10 months. You need to drink that every single hour. How on earth did no one pick up on this? Snape thought Harry was stealing ingredients? That's bulk supplies not a single batch. Also, just that Harry needed to be led through the entire tournament only to have him show up at the graveyard in bloody June. Once again Voldemort proves he's an idiot. Seems like there would have been a better, more efficient way to get Harry to him--especially since he did have Crouch there at Hogwarts. /rambling rant ;)
