Catastrophe

What kind of stupid term is Snowball Earth...? I was sure it was a trumpet translation;

Everything is too slow. One and a half thoughts are so chewed up, so much anticipation, that by the time they finally tell you what it was all about, it's not interesting.

That the last episode is about nothing at all. A repetition of everything that we have already seen and heard. I didn't see any special development of the topic either.
The last experiment is too childish. They would have either clearly shown the scale, or at least named it. For example, with the thickness of the ice, as in those days, there would be a crater of such depth. Well, it would be more logical to shoot at a ball rather than at a plane, because the Earth is a ball, right? It's done with a blunder.

The asteroid impact turned out to be much more impressive and large-scale than the collision with Thea, which is surprising.
It's really not enough to show maps and scales intelligently. That's what prevented you from showing on the map where the asteroid supposedly fell and what area was affected, the size of the crater and everything else? It's all in numbers, but you just sit there and imagine.
At the same time! When they show a planet and a catastrophe supposedly occurs - that a collision with Thea, that an asteroid, shows modern continents and even islands :// Are you serious...?
God, how beautiful the sinkholes are! I wish I could visit a place like this...Magic.

As usual in this genre, there are a lot of repetitions, especially visual ones - of course, it's expensive to draw all these models and simulations, but repetitions of the same thought could have been avoided.
The idea of hours and days is good, but somehow I didn't notice its particular benefit. They remember a couple of times during the series, the time either does not change at all, or jumps by half a digit at once.
The corals are amazing. How scientists see these rings, I see 9 rings, maybe, but definitely not 365 ...)))
