NOTHING Harry does helps his own cause, for example. Harry is never allowed to be proactive. He gets held back time and time again until someone or something ELSE shows up to give him the means to succeed.
You know who that sounds like?
Indiana Jones in 'Raiders of the Lost Ark' (one of the greatest films in existence).
The entire movie is one failure after another for him. He gets the idol stolen from him at the start. He loses the girl, and when he finds her, can't even rescue her. As soon as he finds the ark, it's taken from him. He gets it back briefly only to have it stolen again, along with the girl. He gets the upper hand on the Nazis, only to surrender in about one minute. Finally, he wins by being tied up and closing his eyes.
What a loser, right?
Well, says your analysis, anyway. I consider it a brilliant film and think you're a bit daft for suggesting that it uses a flawed formula.
It's not the same thing at all.
Indy is a smart, educated, adventurer with many skills and abilities to fall back upon, plus years of experience to draw upon.
Harry is a clueless kid whom Rowling KEEPS clueless by having those in charge of his life do little or nothing to prepare him for the role he has to play in the story. Moreover, their decisions often actively HINDER Harry in terms of his development. Harry is left to get by on luck and "fate", not any skill or attribute he posesses or develops by his own efforts.
For the most part, I think we're going to have to agree to disagree about the Potter series. I've come away from multiple re-reads with nothing but appreciation for the depth of the characters and their motivations.
In the first 5 books, I'll agree with you somewhat. However, Dumbledore admits in OotP that he was doing it and that he was wrong for doing so! That's the whole emotional point of the "showdown" in DD's office, where the old man blames himself for Sirius' death. Following that, DD does work with Harry directly, and the OotP treats Harry as a full grown wizard, doing everything in their power to prepare Harry for what must be done.
Beyond that, I think Rowling went above and beyond throughout all seven books to show Harry as an exceptionally competant wizard for his age. They repeatedly show from GOF on that Harry knows more defensive magic and has superior Defense Against the Dark Arts skills than most 7th year students. I don't think it's at all a matter of being "kept clueless" as opposed to Harry actually being a child!
As to the point you are making in your other posts about writer ex machina... doesn't that actually describe all fictional works? Not trying to be difficult, but... doesn't all literature go where the author wants it to? I do get the point you're actually trying to make, that you would have liked things to be more character driven as opposed to plot driven, but I have two counter arguments for that:
1) I disagree pretty much wholesale with the notion that this is a bad example of plot-driven fiction. Almost nothing was introduced that wasn't foreshadowed in some capacity. One could argue that the Deathly Hallows themselves were a piece of deus ex machina that weren't alluded to earlier, but even that isn't entirely true. As early as the first book, people knew there was more to the Invisibility Cloak than we were being told (i.e. if Dumbledore knows of other ways of being invisible, why did he have James invisibility cloak in the first place?). Also, the Hallows turned out to be a red herring, with only the Wand being truly important to the ending...and wand lore coming into play was hinted at in the GoF duel! We knew they couldn't duel again with their own wands.
In my opinion, that's one of the more elegant things about the series. Having Harry being an outsider to the world of Magic, we learn things as Harry does. He's our window into the world. Most of the things that were "dropped on us" suddenly can very rationally be explained that there was no way someone from a non-magical family would know it, and it never had a reason to come up in casual conversation before for Harry (and by extension, us) to know about it.
2) A very large amount of excellent fiction is plot-driven, as opposed to character-driven. Hell, I'll just reference Raiders of the Lost Ark since Small White Car already brought that up. Yes, Indy is established early as being a confident, competant explorer... but Fate and Luck are what drives the plot of the entire film! Marion just happens to still have the exact medallion Indy needs; The German just happens to burn a perfect facsimile of said medallion on his hand; Indy just happens to have a friend whos the best digger in Cairo, et cetera.
I am OK with you just not liking the HP series, that's certainly your prerogative. IMHO, however, your arguments as to it being poorly written don't hold any water.
