70% of this show is about Earth and how the planet and everything on it adapts to hostile and ever changing circumstances and how this might be similar on other planets. And 'might' is the key word here because they present these alien worlds like they've actually been there when really, it is just something that could be and not something that surely is. Interesting for sure but not very convincing and pretty far fetched at times.
The thing that bothered me the most is that they overuse the images from the alien worlds to such an extend that is becomes ridiculous. If you would condens the unique material of the alien world for each episode it would probably just be 5 minutes. In the second episode I started tracking how many times they would use certain fragments and some are used more than 10 times throughout the episode.
So in the end this feels like a documentary about life on earth in hostile situations. With some cool images from made up places that could be in our universe.
