EXPANSE SPOILERS:
Episode 4 was great overall. I have a couple of comments/observations though.
First, is it just me or have they pretty majorly nerfed Inaros' attack on Earth compared to the books? I'm not sure I understand why. They took a giant "holy shit" event from the books and made it, I don't know, less intense. Seems antithetical to TV writing.
Second, I wish they had decided to spend the VFX money they've clearly laid out for season 5 when the shot season 4. One of my big disappointments in season 4 is that the robo-Miller on screen was super lame compared to the books. That droid thing in this episode looked fucking awesome.
