Adrift is a better episode than the choppy first, it is paced better, acted a little better and sets up the story going forwards. Like episode one, Nori is still the highlight so far, and I though the scenes with Elrond and Durin were pretty funny and well done. The scenes in Khazad-dûm were the best part of this episode, and they very much felt like they belonged in the Hobbit Trilogy. The sets and quality of the visuals during these scenes were fantastic, so props to the guys responsible for carrying these few episodes.
That being said, Galadriel is still boring, as is the elf warrior guy - Arondir and his weird relationship with Bronwyn.
We got an opening title, with was ok, but getting to hear Howard Shore do some more LotR music was a joy, and it's glad to see he hasn't lost his touch. The rest of the music, done by Bear McCreary is also very good, but this should be expected by the guy who composed the music to a much better Amazon show, The Outlander and the video game God of War.
Adrift was just fine, not great, not bad. I do hope the episodes get better going forwards, but I think Amazon should have released 3 episodes instead of 2, because I'm still not invested in these characters or the story.
