Salvation is a TV series on Amazon Prime. The first season is free. I'm watching because it's not that good, so when they start charging I'll stop watching. It's kinda like when you are beating your head against the wall, and someone says if you keep doing that you are going to have to pay for the damage, so you stop.
Here's the plot summary. The earth's in trouble. Again. An asteroid will destroy the planet in six months unless humanity destroys it (Planet Earth) first. Granted, that's a tight time frame for man-caused planetary destruction (it's OK to use "man" in this context) but doable. So the asteroid is actually "plan B from Outerspace."
It's the size of Washington DC and will impact Washington, DC, which sounds good until you see the simulation: the entire surface of the planet turns into molten lava! OMG, not even a dinosaur could survive that! There's always hope, though.
Hope, in this case, is a deep space probe out by Jupiter that can be redirected to crash into the asteroid. This is like a bullet hitting a bullet, with one bullet being the approximate size of an empty tin can and the other being the approximate size of a fully ladened supertanker. But, if you take into consideration their high speeds and something called "inertial mass," which has something to do with something called physics, then the Asteroid breaks apart and the resulting impact no longer destroys the entire planet or kills all 12 billion of us (and our pets). Instead, the pieces miss Washington D.C. and hit Beijing and Moscow, killing 1.1 billion of those people (and their pets). When this possible outcome is described at a Pentagon meeting, everyone goes hmm at the same time. They decide on this collision course. Unfortunately, there are many collision courses!
President Biden is totally out of the loop and uninvolved, as you might expect. They could have had Martin Sheen play him (he's old enough) if only there were a believable plot device like his getting briefed. His absence is explained in episode six when he's referred to as a "she." Apparently, he begins self-identifying as a woman because that description is easier to believe than honest, moderate, and competent. Also, he can now freely sniff women's hair because a woman can do that to another woman, can't she?
During this period of Presidential transition, government agents and billionaires do what they want with government resources. This is quite realistic but they should call it "infrastructure spending." Also, the deep state is deeply sinister. That's the sort of portrayal that annoyed me ten years ago, but these days, not-so-much (thank you, James Clapper and John Brennan).
