ETA 9/13/15: I got over it, :). I had a mad urge to watch it recently and while I noticed the error (it's impossible not to), I was able to gloss over it and enjoy one of my favorite movies of all time. Which brings me to something else - how the FUCK is this POS one of my favorite movies of all time? I think it's the cast chemistry. The movie does have an AMAZING cast who took this movie and absolutely ran with it, taking its incredibly silly premise 100% seriously the entire film and that helps a lot, :).
As some of you may or may not know, I really love disaster movies. Always have since I was a kid. I'll watch and enjoy any silly premise out there, from "Armageddon" to "Volcano," from "The Towering Inferno" to "The Poseidon Adventure," but the one that I've found holds a special place in my heart is "The Core." I actually own two copies of it (pan and scan, purchased by accident, and widescreen) and have found myself watching it recently when it's been on cable.
( Or why I can't enjoy a hot mess of a movie the way I used to anymore... )
