And yes, you're right. Some of the low budget episodes in the Star Trek franchise - also called 'bottle episodes' or something for some reason - are some of the best and most memorable episodes.
These 'bottle episodes' used mainly the same sets that were already built and used none or very few guest actors. This was to compensate for episodes that had gone over budget earlier, or were planned to go over the budget per episode later. Only proves the writing is the most important thing.

Yulin's performance was simply perfect.
