I am a big fan of the series, as my other reviews will show, but I have to say that the abysmal acting skills of Strait (Holden) are putting somewhat of a damper on my enjoyment of Expanse. In this episode, he spent all the time clenching his jaw and making idiotic commands which could have gotten everyone killed---and for what? There is no way he could believe he was about to get rid of the last of the protomolecule, so why bother with one source? It doesn't make sense.
I like the arc of the plot with Bobbie claiming exile on earth. Ashdagloo has grown in her role, and I look forward to her scenes more than most others. The actress who plays Naomi is also pretty boring, but not as bad as Strait.
I have to say that I have found the series bland this season, compared to season 1. I think the acting has a lot to do with it. Miller was such a fine character, and now he is gone. Errinwright is OK, but not at the same level. Jared Harris, another fine actor we haven't seen for a while.
I am looking forward to the closing episode, and hope the arc of the series goes higher next year.
