My biggest problem with this movie....
...was that in the 90s, when disaster flicks came out, much of what you saw was based on actual science, and were even inspired by real-life events. Movies such as "Dante's Peak," "Twister," and "Volcano" were interesting and semi-believable. "The Core" was a little less believable, but what the plutonauts in the story got to see as they tunneled through the earth's various layers is based on what we actually know about our planet's interior.
I also studied weather extensively as a kid, and this movie's BS weather really made me squirm, the "science" was soooo badly-written.
