Brought over from episode 1 Dulcinea thread since it discusses book specific things.
A story told on screen will require different things than one told in print. This is an adaptation so changes an adjustments will need to be made in order to effectively relay information. With a few changes and two or three minutes of screen time, we have some big world building, tons of character development and exposition and set ups for future possible plots where in the novels this stuff was laid out over hundreds of pages and across five different books and counting. Space is harsh, space is dangerous, there are pirates who don't hesitate to attack and kill making it very dangerous to answer distress calls. Then there's Holden, a seemingly unambitious man who has trouble following the rules and often thinks in black and white without fully considering the consequences of his decisions. In a few short scenes, we know who Holden is, which isn't yet different than who he is in the books. The few changes are not relevant and don't cause big changes to the overarching plot.
Naomi is not a change to the plot, though the way the interactions went on the Donnager is different. Naomi is a seeming mystery. She's mega smart and has several advanced degrees in the show and the books, and yet she's working on a shit-ship like the Canterbury. There has to be a reason, right? Just like there was a reason that the once ambitious Holden found himself comfortable working on the Cant for five years. The careful viewer would already see that Naomi's neck tattoo is enough to make one question whether or not she has a connection with OPA. In Leviathan Wakes, the Roci crew works directly with OPA. In later books, the pasts of the various characters are examined. We learn much about Naomi.
We also continue to learn about the OPA. The first few episodes treat them like only a terrorist organization. It's similar to in the books. Until we learn more.
So far, I really think the adaptation is working well. All of the changes make sense. The characters are roughly as I imagined. The only major issue I've had is the crash couches. They are such weaklings when they should be big things and I'm annoyed by the characters turning their heads and moving around when in high g burns. I'm guessing the process of filming and editing required the crash couches to be barely visible around the cast so I can live with that.
