This was honestly one of the worst movies I've ever seen. The script is stupid, even for a popcorn movie. I can get into a far-fetched idea, but this pushes the limit. With some decent execution, I might have forgiven the stupidity of sending a craft of people to the center of the earth. Maybe it could have been saved with some cool effects, but they were simply awful. Maybe it would have worked if Eckhart and Swank would have played up the camp factor of such a ridiculous project, but instead the went for soap opera-level overacting. At a 5.3 at the time I'm writing this, The Core has to be one of the more overrated movies on IMDb.
