Science in movies almost always requires a suspension of belief. The worst offender is how they make so much noise in space!

The very worst science movie I have seen, at least one based solely on special effects, was "The Core." Everything was grossly wrong there and required suspending one's entire intelligence. That's pretty bad considering I am a life-long Doctor Who fan!

As for Dante's Peak mentioned in the article, there is one scene I remember where he is outrunning a pyroclastic flow in a jeep! That must have been one really souped-up engine!
