Good post, Michael.
I also thought they pulled off the darker feel, but personally I feel it should have stayed lighter (remember, I haven't had the books 'taint' my impression of the movies. I'm serious.)
I don't think that what they presented in the first film can necessarily withstand an assault on its characater and spirit by having so many dark elements thrown in the 2nd film.
Each time they have a dark element, it jars me out of this happy, safe, kid-like heroic story-world that they presented in the first film.
The sets WERE great, especially the Chamber with the huge snake-heads. I kept saying to my wife, "Geez, is that a SET?!"
Tom Riddle WAS good, and actually just about all the character were good (I didn't know that about Dumbledore's book personality).
The problems I have (Enchantress...) are with the jarringly-bad STORY.
It's like they have this beautifully-layed out castle, world, and characters, and their actions are being directed by a nincompoop who has no understanding of rational actions.
For example, why would they repeatedly show spiders leaving the scene of the crime, and NOT have Harry follow them? Or even point them out to his 'trusted' superiors?
If they AREN'T trusted (i.e. Dumbledore), than they have just broken one of the conventions they established in the first film.
Further, why WERE the spiders there at the scene?
They weren't involved in the crimes (as established in the "Spider-Scene"), so why did they show Harry repeatedly seeing them leaving a proverbial trail of crumbs that he kept ignoring?
Enchantress, it's not asking for perfection in a movie - if you think that it's asking much to not present a story that has a frickin' CAR act as the Hand of God and pull Harry and Ron's butts out of the fire that HAGRID HIMSELF threw them in, than you really should look at the movie without rose-colored glasses on.
That's not a quibble.
That's not a 'gripe'.
That's an insanely stupid scene, with HUGE story problems created because of BAD direction combined with BAD writing.
(to wit:
** Hagrid basically mudered the kids by sending them there.
** Army of flesh-eating spiders in close proximity to kid's retreat.
** Car being omniscient.
** Bad looking big spider.
** Why is Hagrid friends to an army of Evil spiders? (eating schoolboys qualifies as a sign that they are Evil, in my book, how bout yours?)
Michael - you mentioned the bad acting of the boy Malfoy.
I was confused at the end of the movie - Harry calls the older Slitherin "Malfoy" - I'm sure of that.
But when I heard it, I could have sworn I remembered them calling the younger blonde boy Slitherin "Malfoy"?
I already mentioned that I liked the racism/classism angle - lots of good grist for drama there.
Here are some other problems with the story, not with the execution (for the most part):
1) Why would Harry even think about going back to those horrible people during the summer? They showed him being systematically abused, and then send him back home at the end of each movie??!
It makes no sense - here's a world where everyone reveres Harry like a celebrity (he's even got fans), yet he has to go back to Abusive-Muggle-Land in the off-season?
Not damn likely - He'd stay at the school, or with the Weasely's
2) Why did Dobby go WAY out of his way to 'protect' Harry?
At that point in the story, Harry wasn't in any more damnger than anyone else at the school, right?
As far as Dobby knew, his master was going to give the Weasely girl Riddle's diary and have her open the Chamber of Screts.
How does that endanger Harry more than any other student?
He SHOULD have been warning the Weasely girl.
3) The afore-mentioned flying car in front of the train scene.
4) It was jarring to have the Tree they smashed into be such a menace.
Why would they allow these things on the schoolgrounds if they would kill the kids that go there?
5) Why is so much story happening in the girl's bathroom?
6) Why did ALL the students spontaneously show up in the hallway right after the first attack? Some internal Trouble-Alert in the school?
7) The Powers That Be never knew that TomRiddle (their own student) grew up to be Voldemort?
8) They never thought to look at the big piece of paper crumpled up in Hermione's hand?!
9) Something smacked me as wrong about "I am Lord Voldemort" being created from his Muggle name, and I can't put my finger on it.
10) Harry and Ron were uncharacteristically aggressive with Lockhart. They actually pushed a grown adult male BACK? Then pushed him down the open well that they didn't know what the bottom was?
Further, WHY would Lockhart have been frightened in any way by being 'guarded' by Ron Weasely and his broken wand pointing at him?
11) The Chamber of Secrets scene:
a) I didn't like Harry dropping his wand while looking on the girl - too stupid, and he'd be unlikely to drop the only thing that makes him different from a normal little kid.
b) Speaking of just being a Muggle, it was quite insulting to the viewer (IMO) to have the entire film's drama resolved because a little kid kills the Basilisk. There is NO WAY a normal kid could kill this monster that frightened generations of powerful mages.
They never should have had the drama resolved by relying on Harry's physical skills.
It would be like Luke defeating the Emperor by taking out a book and studying him to death - it doesn't fit, and Luke's schtick is not being good at reading.
c) The Phoenix conveniently showing up and blinding the Basilisk.
Another example of Deus-ex-Machina in the story.
d) The Pheonix's tears (?!) healing Harry from certain death - another deus ex machina.
12) This whole concept of Voldemort creating a diary which "contains his 16 year old self" is problematic.
If he can create a diary that could take over any kid and make him live again, than he effectively can never be destroyed.
BTW: HOW did the girl get taken over by the power of Voldemort, yet somehow escape the power to throw the book away so Harry could find it?
Now some of these might be explained by info from the books, and Id be happy to hear from anyone who has read them and can 'correct', or explain any of them.
