I'm surprised at how un-"self-aware" they're playing this, for the year 2017. It goes by without question that aliens Earth knows nothing about speak English and behave in a ways comprehensible to modern Americans. Noone questions why aliens have a giant hardcover book bible that's read from left to right unlike Hebrew or Arabic or other non-"western" languages. They're playing the show like Gene Roddenberry is still alive and overseeing everything.
Did anyone else think that when Isaac suggested mating with a human woman, they were making a reference to Data and Tasha Yar in that early TNG episode?
