What bothers me the most about this episode is that it feels like total character assassination of Spock and Vulcans. Yes, Spock is half-human, half-Vulcan. But that does not mean that he is dumb or inferior. He is a highly competent Starfleet officer and very intelligent and logical as we see in TOS.
And considering how in the last episode, Spock admits that he mutilated himself to try to excise his humanity because of how Vulcans mistreated him, it is rather uncomfortable to see his human friends turn into the worst stereotypes of Vulcans and do the exact same thing to him in this episode. They repeatedly mistreat him for being half-human at every turn in this episode and it is played as a big joke. "The away team is only 4.5 Vulcans because you are only half Vulcan, Spock, you are inferior to us and not a real Vulcan like us that took a magic serum!" Vulcans are turned into horrible stereotypes rather than the stoic, wise and highly intelligent species that they are.
