Amiel's film is a messy, speculative chamber piece augmented by indistinct visual effects and performances that seem to be playing directly to the blue-screen backgrounds instead of to the actors who were hired to make the highfalutin conceit plausible.
Despite the boisterous production values of this overwrought and unevenly irreverent disaster B movie, The Core never really shows us anything worth exploring under its nonsensical albeit volatile crusty surface.
Some science fiction films are supposed to be fun. These are throw away films; films to take to your mind away from the things we face in real life. Go with this thought and you will enjoy The Core. If not, then this film is a complete mess with no hope
