When I was six, I was told that if you were ever in a runaway elevator, you wait till you are just about to crash, and then jump onto the bottom floor. That's the scientific principle at work here. Wait...there are no scientific principles. People keep saying what a great movie it is because it has such great characters. What it has are a group of stereotypical beings that you can find in virtually every disaster movie ever made. Science fiction does have the word "science" in it. This is a great movie if you don't think about the five hundred impossibilities that permeate it. It was disappointment to me as a child and it still is.
