Episode 3 was classic Trek. Taking a modern issue and putting it into their fantastical world. The ethics of the story, as the show points out, are pretty cut and dry in our society, but in the case of a race like Moclans, it gets a little more muddy. One can only hope Discovery can pull off an episode like this.
As for being early and the idea of making us feel for Bortus, I think that misses the point here. It's not about the emotional impact of the characters, it's the emotional, and moreso the intellectual, impact of the story itself. Considering the ethics of the events and even the history behind it is just as satisfying for me as a viewer as emotional impacts of characters, whether 3 or 300 episodes into the series. The subject matter is bold and was handled very well (for the most part). I think one also has to note that it's probable that Fox executives might have had as much or more say for the order of airing as the creators, so there's that to consider as well.
That said, I will still offer a couple of my own criticisms: the reasoning and events in the court room were fairly problematic. For one, there was no exposition on the Moclan's legal system, so figuring out what was legitimate courtroom behaviour and what was not was hard to figure out unless you assume it is near analogous to our own modern legal system (in which case, it was horribly done). There was a lot of poor argumentation from both Kelly and the Moclan prosecutor/plaintiff that stuck out for even someone like myself with some but not extensive knowledge of legal procedure.
The one thing I will unashamedly state is that Bortus and Klyden's interactions throughout the episode, whether with each other or Bortus talking to other crew-members, was very well-written.
I do wonder how much this will be brought up again, not to mention how involved the child will be in the series. It does bring up not only a lot of questions as a viewer, but a lot more possible options for the creators and writers.
