So the fifth episode was a slight step down from the excellence of the fourth episode, but it was still quite good.
The crew stuff was fairly slow. It was obviously an "in transit" episode where they try and come to grips with where they are and what they should be doing. As such, very little actually happens -- Naomi has to make a decision... and that's about it. I did like the scenes of the crew coming to grips with the new ship, and I especially liked the expression on Holden's face when he finally found all the coffee.
I was a little disappointed with the interior of the Rocinante. I thought it looked a little too much like a hotel lobby and less like a warship, not to mention the fact that it was utterly dissimilar to the interior of the Donnager. I'm glad that they gave it its own character and made it different from, say, the interior of the shuttle, but it feels a little "off" to me somehow, especially those lozenge-shaped dining tables and the avant-garde herb gardens built into the walls.
But I guess if you're going to be filming something like 40% of the series' scenes in a place you'll want it to have some distinct and recognizable features.
Miller's stuff was a bit more interesting, and I liked that they are showing the slow break-down in order on the station (though I think they could have done better). I'm personally pleased that they are showing us the details of Miller's investigation, and the scene where he explains the two ships' trajectories to his ex worked very well for me... but I'm pretty sure that most of the episode could have been boiled down into a 60-second "investigation montage" and we'd be not much poorer for it. I did like the interview with the pilot though; that went a long way towards showing Miller slipping into obsession.
The flashback with Anderson Station was fairly well-done, though I think some of the actors were a little too "on the nose": we didn't need both the adorable moppet and also the father with ultra-soulful eyes to convince us that these were not desperate terrorists; either would have sufficed, or neither for that matter. I'm hoping we'll get the other half of that story later on - anything that gets Chad Coleman more screen-time is gold in my book.
