I was very apprehensive about renting this movie after so many mindless apocalyptic special effects movies in recent years. Most are all effects and brawn; no characters or brainpower. The Core has it all. It's based on a lot of real science. It has good character development and you actually care about the people. It is about smart people solving problems. It has a lot of great tongue-in-cheek humor too. On the extra features, they said they were trying to make a 1957-style SciFi flick and they succeeded pretty well.
