The Worst:

1) 2012 (2009): Neutrinos from a solar flare heat up the Earth's core, setting off the end of life as we know it. The plot conveniently ignores the fact that neutrinos pass straight through matter—even us—without doing much of anything.

2) The Core (2003): The Earth's core has stopped rotating and scientists have to drill into it to start it back up. The moviemakers go nuts with basic geology, ending up with something the New York Times called “monumentally dumb.”

3) Armageddon (1998): A team of drillers is sent to an asteroid on its way to strike Earth to split it into two parts they say will fly safely past the planet, completely ignoring Newton's First Law of Motion ("an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force"), which says that all they did was make two asteroids that would hit the Earth.

4) Volcano (1997): Los Angeles is destroyed by a volcano that springs up in the city. Bad science mingling with cheesy dialogue and effects.

5) Chain Reaction (1996): Keanu Reeves. Bubble fusion. A government plot to prevent the spread of the technology. The perfect recipe for bad.

6) The 6th Day (2000): Arnold Schwarzenegger is cloned. Because one of him just wasn't enough?

7) What the #$*! Do We Know? (2004): Read the synopsis on Wikipedia. It'll make your head hurt.

And the Best:

1) Gattaca (1997)

2) Contact (1997)

3) Metropolis (1927)

4) The Day the Earth Stood Still (1951)

5) Woman in the Moon (1929)

6) The Thing From Another World (1951)

7) Jurassic Park (1993)
