I enjoyed the episode. The problems that people above wrote about, I noticed -- but didn't detract from my enjoyment of the episode.
This sums up my feelings as well.
Brian Gross and Jacy King were good as Kirk and Marcus. I really liked Brandon Stacy's take on Spock in this episode, and I enjoyed the Ferengi commander (I suppose he was listed in the end credits as "Alien Commander" played by Clay Sayre). The starbase model was cool, clearly a kind of super-sized K-7. The proto-life-support belt effect was also well done. Oh, Kirk putting his boot on got a laugh out of me.
The ambiance and pacing were generally excellent and kept me engaged. This compensated well enough for problems in the story noted upthread, such as the accelerated romance and breakup and the solution to the mystery of the explosion not resonating because we didn't know DeWitt at all. Continuity issues that would arise from trying to integrate these events into canon, such with as David's age and the evident need for the Ferengi to have been forgotten, as discussed upthread, those didn't faze me in the slightest. I don't know why Captain Scott bookended the episode, but I enjoyed that nevertheless.
Clearly, "The Holiest Thing" is largely a prequel to
The Wrath of Khan, but another interesting thing about it is that it puts a novel twist on the reveal of David's use of protomatter in
The Search for Spock that reflects back on Carol. Two of the nagging and unanswered questions posed by TSFS were: how much did Carol know about the use of protomatter and when did she know it. While THT doesn't provide any definitive answers, it certainly opens the door for her intending to actually sanction use of the stuff herself. If we read between the lines, Carol seems just as driven as DeWitt, as well as the terraformers seen in TNG "Home Soil." I think a more complete view of Carol's character could have come from exploring this aspect, of whether she herself actually intended at this point to get her hands dirty by working with protomatter, and furthermore of whether that had any bearing on her insisting that she would be unable to do her terraforming research aboard the
Enterprise. In other words, the question is, did Carol's realization that she could perfect her technology by crossing ethical lines influence her decision to run away from Kirk?
Actually, the biggest thing that detracted from my enjoyment was that the lighting level seemed too high sometimes, such as in sickbay.
Congratulations, thank you very much for the fine effort, and I look forward to your next episode.
