Disappointing Episode after a Thrilling Pilot
15 November 2014 | by anmolkohli01See all my reviews

I earlier wrote a review for the pilot, and I gave it a 9 out of 10.

I may be against this episode because I am more of a Physics guy, and never had much of an interest for Biology. That being said, evolution is a fact. It has been proved correct, and nothing, written in any old "sacred" book, can prove it wrong.

The script is similar to the pilot, without the planets/systems/galaxies/universes/multiverses/bubbleverses mumbo- jumbo. It shows the "Tree of Life", a needless to say, tree which gives birth to all life.

We see how the polar bears and dogs came into existence, this ultimately leads to the discovery that all of us are related to each other(yummy yummy incest).

We then look at the broken branches of the tree, that is, the extinct species. The last of them didn't have a name, which was clever, I think that was reserved for the Homo Sapiens.

In the last 6 minutes, they show us the possibility of life on Titan, the largest moon of Saturn. I would like it better if they researched on Europa(moon of Jupiter) or Enceladus(moon of Saturn), as they are more likely for life there than anywhere else(after Earth, that is). Maybe this could be the plot of Christopher Nolan's next movie, Interlunar.

This segment was rather crammed, and I would like it better if they made a whole episode out of this, instead of filler material.

The script, on paper, sounds perfect. But the episode just did not have that feeling of wonder, of excitement, that the pilot had. It could have been much, much better.

Crammed segments, overall dullness, and uninteresting topics earn this episode a 6 out of 10.
