I really liked the previous one, especially the one with the "darmok and jalad at tanagra " species. But also the mugutu/muguta/Maguta one.
I found the premise that people talk in metaphors (Tamarian) okay, but I don't understand how they would teach such a thing to their kids. It felt like Kadir beneath Mo Moteh.
To teach you could use the phrase when observing the behavior, but that leaves a lot up to the imagination.
There is a book that describes they act out a play to teach kids these meanings. And that we should compare it to the written Chinese language, where combining two different words convey a different meaning.
But I don't know Chinese, so I assume they also just learn the meaning of this combination. And some meaning can be derived from it's radicals.
In Japanese they use Hiragana to makes this part easier, and in Chinese I guess they'll start with the easier radicals first, but non of this is mentioned for Tamarian.
And using metaphors somewhat implies they should be able to understand non-metaphors also.
If they have names for people (Darmok, Jalad) and places (Tanagra), you should be able to create new metaphors instead of just historical ones.
Which they actually did (Picard and Dathon at El-Adrel), but as no one knows the reference to Picard how would others understand?
I probably thought to much into the concept while watching this episode, but I still found it entertaining. The constant repetition was somewhat annoying though.
