In general, I have very few complaints about the adaptation of the novels to the TV show. There is one scene from the prior episode where I would have wished that it was closer to the book, and that was when Gunny sees the Protomolecule on Ganymede. In the book, Protomolecule Man picks Gunny up and in the process of this interaction, it hurls her a large distance, which simultaneously seriously injures her, but actually saves her, too. It reinforces her memory of Protomolecule Man, as well. In the show, in the small snippet of the battle, Gunny sees the UN team FIRING BACKWARDS, but she is prevented from elaborating on this during her questioning by Martens or her testimony to the Earth and Martian diplomats. This might mean that many viewers didn't completely catch that either. However, I fully trust that the writing and production team will integrate this information into the ongoing story.
As usual, a rewatch is invaluable. Watching once gives the broad strokes, but this show is full of subtlety, easily missed, particularly if viewers live tweet. My recommendation is to watch twice. At a minimum, make sure you watch this show carefully at least once. This episode was all about people being short-sighted. Errinwright and Sorrento-Gillis don't fully grasp what is going on, and Janus doesn't understand what is happening on Venus. People's limited views have really significant impact and this is setting up the continuing storyline. In the meantime, large swaths of people are impacted by events which have been set in motion. I'm looking forward to seeing what action Avasarala will take in reaction to her clear disbelief in Bobbie's story AND her concern over what is being observed on Venus. Also, what will the crew find out on Ganymede?
