This is one of the more relevant questions IMHO.
I thought that Armagedon was one of the worst action movies I've ever seen (could I _please_ watch the D&D movie instead?). As much as I love the idea of a blockbuster written by someone on these boards, this movie looks about as good as Armagedon.
I think my only major heartburn with the movie is the entire notion that the core of the earth _could_ stop rotating independant of the rest of the planet. This seems like the worst sort of psuedo-science (or non-science) and has received many jeers from my circle of friends. Of course, we all know that some of the weirdest notions prove true science, so I'm all ears if someone can throw something in the way of justification for the foundation of the movie.
First, vis a vis xeriar's notion of "swirling" vs. "spinning" outer core, that's one of the things up for grabs in current research. We also make a point of saying it's not solid, as you know and point out in your post. It's also not transparent -- those are the imaging viewscreen views (one or two might not be, but hey, sci fi's sci fi.)
The bombs don't generate a current -- they re-establish motion in a non-linear fluid dynamic system of the outer core. It's a little fast-and-loose, but a hell of a lot closer than the "split the asteroid the size of texas with a single nuke" gig. Once again. Sci fi. You don't choke on faster-than-light travel in space movies, you won't choke on this. Of course, if you do, then you're an enemy of fun.
The outer core also, as xeriar points out, does change rotational axes every half a billion years or so. That's why our north and south poles flip. I'm a little confused over your assertion that that movement isn't primarily responsible for the geomagnetic field, but I guess research sources can vary. The JPL guys seemed okay with it.
No extinctions can be tracked to the reversal, but that's because it's always gone smoothly up to this point. As for the effects from the collapse of the electromagnetic field, google up "Dr. Marvin Herndon". He recently published a peer reviewed paper for the Academy of American Scientists which proposes a potential collapse of the geomagnetic field (from a different origin than ours, but the same end) and confirms that the ensuing disasters would not only be similar to the ones in the flick, they would be worse. Nice bit of synchronicity actually.
All that said --
it's a frikkin' journey to the center of the earth movie. If you're reading and posting on these boards,
you pretend to fight orcs in your basement. I'd ask for a little suspension of disbelief. Where we could keep the science real we did, and where we couldn't we bent it rather than break it. The primary difference between our flick and
Armageddon is that they assumed you're too dumb to know when they're making up science, and we assume you're smart enough that we have to at least lie to you convincingly.
And even more importantly, the actors are fantastic, and they're not the disposable redshirts of most disaster flicks. You will remember what happens to each of them, and the choices they make.
It's a big, 1960's fun sci fi movie, smack dab between
Andromeda Strain and
Fantastic Voyage.
Glad you liked it, Barsoomcore.
