Asteroid headed for earth, can't destroy or move it so we move the planet. Like you're driving a Suzuki Samurai and come upon a 20 ton boulder and decide it's easier to try and move the boulder, than the vehicle.
I like the scenes in the submarine when it gets rocked back and forth in one scene, and in another scene, rolled over after getting hit by a tsunami, how the free standing computer monitors, the crew sitting (unstrapped) in office chairs (that are not bolted down), manage to basically stay in one place.
