The Core (movie released 2003)
Geophysicist Dr. Josh Keyes (Aaron Eckhart) discovers that an unknown force has caused the earth’s inner core to stop rotating. With the planet’s magnetic field rapidly deteriorating, our atmosphere literally starts to come apart at the seams with catastrophic consequences. To resolve the crisis, Keyes, along with a team of the world’s most gifted scientists, travel into the earth’s core. Their mission: detonate a device that will reactivate the core.
But Rotten Tomatoes said:
Is Core a good movie?
The Core has a great cast of talented actors, but even that doesn’t save this lacking, and mediocre story. This is one of the worst action films that has come out of Hollywood, and really makes the disaster genre an irrelevant bad joke. This is a film that should be avoided.
“The Core (movie released 2003)”
Yeah, I watched that pile of dog crap of a movie. Well, part of it anyway. Dang thing kept putting me to sleep, though the acting did give me nightmares.
