I was away all weekend, so I didn't get a chance to watch it until now. I liked this episode.
The Karnak plot wasn't the strongest in the past, but it was nice to see his powers returning. I also liked the idea of Karnak learning to be more like Gorgon and Gorgon learning to be more like Karnak.
I also liked that they are addressing some of the issues with the royal family and whether or not Maximus is noble. I wish all the noteworthy Inhumans weren't on Earth, though, because the plot of the resistance to Maximus could be interesting but likely will feel to small. The problem is the show feels both too slow and too rushed with cool elements not amounting to enough. Tybor (or whatever the Genetic Council guy's name is) and the resistance are nice little moments.
The only plot that didn't work is Crystal's. There were some nice touches. Since Crystal is the most innocent and ignorant of the world, she can be the most frank. She can flat out say that the big issue is Inhumans fear humans, which is the reason they're on the moon. But, as disappointing as Crystal's acting has been, Dave is much, much worse. He's probably my least favorite character.
BTW, what happened with echolocation girl getting shot? I somehow missed that.
