But actually, they don’t. If you read it carefully, on the first go-around of the night’s events, everything happens exactly the same as it did the second time, you just see it from a different angle. If that makes sense.
I agree with pretty much everything that’s been mentioned so far, especially Grawp and Quidditch. And even though I love the series (my username is from Chamber of Secrets), I have a few of my own to contribute:
Philosopher’s Stone: The whole setup of interesting obstacles that just happen to match the kid’s special skills hiding the Stone. I mean, really?
Chamber of Secrets: Harry and Ron go to the staff room to tell them they’ve discovered where the entrance to the Chamber is. Only when they get there, they find out that Ginny’s been taken. So they, naturally…go back to the Common Room to sit and stare at each other mournfully for a few hours, instead of passing on this potentially useful information to someone who might be able to use it.
Prisoner of Azkaban: This one’s minor, but when Fred and George give Harry the Marauder’s Map, they explain that they have it memorized. Which is stupid, because the primary purpose of the map is to tell you where people are, not how to get places.
Goblet of Fire: Most already mentioned. Also, why was the Quidditch season canceled? For all but four students, the Tournament only used up three days in the entire school year. I think they could have handled the load. Geez.
Order of the Phoenix: Okay, so Dumbledore doesn’t want to have close contact with Harry in case it reveals the mind-connection to Voldemort, or something like that. So, dude…why don’t you write him a damned letter? “Yo, Harry. I know you’re seeing all this stuff from Voldemort’s mind. Creepy, isn’t it? Sorry I can’t tell you this in person, but with your connection to Mr. Bad Man it could be dangerous for both of us. Oh, heads up…Voldemort wants you in the Department of Mysteries, because it’s the only way he can get the weapon, so disregard any visions that tell you you need to go there. It’ll be a trick, okay? See ya around!”
Half-Blood Prince: Another small one, but it bugged me that when Harry realized he liked Ginny, all of his internal thoughts were about how Ron would take it. No mention was ever made of her old crush on him, and how stupid he was to have blown it when he had the chance. Or maybe him thinking, “she used to like me, maybe she’ll like me again.” The crush went completely unacknowleged.
Deathly Hallows: The defenses put up by Moody to keep Snape out of Grimmauld Place were pretty lame. And I know most people love it, but Molly’s “Not my daughter, you BITCH!” makes me cringe. Molly is not Ripley, Jo.
God, I’m a nerd.
