Okay, so I saw the movie today and had trouble telling the wife and the mistress apart at first. I liked how the movie repeated all the (in)famous scenes of the original with a twist.

What I didn't like was the trashing of physics with "The Drop" I know it is far above the ability of most here to understand, but let's just say the 17 minute drop is impossible for several reasons. First of all, I did the math, and amazingly enough, if you were to fall for 8.5 minutes at one gee acceleration, then slow at one gee for another 8.5 minutes, sure enough, you could cover much of the diameter of the Earth. They got that right. However, should you be able to fall through the Earth like that, your acceleration would immediately start reducing due to the fact that the mass of the Earth above you would start counteracting the mass of the Earth still below you.

So you wouldn't increase in speed like you would with a constant acceleration. Also, wind resistance would slow you way down. It is apparent in the movie that there is air in the tunnel. And if the tunnel was full of air, it would be immensely dense toward the center of the Earth, perhaps even solid. Then you have the question of heat and radiation near the core of the Earth. And finally, you would, theoretically, feel weightless for the entire journey, for you would be in a free fall.

Finally, the passengers would indeed feel lowered gravity near the core of the earth, then the gravity would reverse, but only if their velocity remained constant, and it wasn't. Also, in "reality" they were traveling along a path that passed only near the core. So if they really could make that fall in a perfect vacuum, what they would feel was a slight lateral force as they would always be falling at an angle to the center of the Earth.

I'll spare further criticisms, but the Fall, as presented, is wrong much more than it is right.

We'll have to agree to disagree about global warming until the next global cooling scare comes along
