The idea on its own is very interesting, and I will definitely pick up the book. But the execution here is off. The show is mostly filler. If you watch the last 5 minutes of every episode, you will see almost all the interesting stuff.

It keeps adding and removing characters and then trying to make you care about characters it just introduced 5 minutes ago. It's only 8 episodes, but for half of the people in the last episode, I had no idea who they are or why they are there.

It should have focused more on the main 4, or even better, choose 2 and focus on them. If this was made as a 2-hour movie and had 2 main characters for the whole runtime, this would be much better.

The characters are also not the best. The story tries to have some character development [spoiler] (two have quite a big tragedy, but forget about it completely within 5 minutes) [/spoiler] but it falls very flat. They also should be "scientists" but they jump to conclusions so quickly without any reasoning, that they sound stupid half of the time. Maybe it is better in the book.
