The coal town story is when her character takes off for me. I think the poor reception to the show was due to the similar characters that the captain and first officer both shared.

Most of the successful driving storylines showcase a dry rational lead with a spontaneous first officer, or vice versa. Kirk to spock, Picard to Ryker, Voyager had it with Jane way and Torres as well as later with seven, and deep space nine is the greatest installment because it was the truest ensemble. All characters swap these roles progressively throughout the series.

Bashir and O'Brien being my favorite duo of opposites, especially since their arcs swap. To start Bashir is some cringy playboy fresh out of the academy, while obriens greatest achievement is he makes the transporters go pbrrrr. Later obriens a veteran who is misunderstood while Bashir is a khan super wired towards john stuart mills level altruism. The blight episode being a real show of "the greater good" as well as others.

In enterprise everyone are fine actors and the chemistry does come eventually, but everyone is relatively dry to other star trek shows, and there is no chaotic injection necessary to spice up the dialogue.

Discovery on the other hand becomes a confused storyline because the emotional investment is so spread out among an entire ensemble of Shatner styled actors emotional actors that you end up begging for a reserved Book or Stammets episode so you can have a point of reference to the emotional bandwidth being used in the episode.

TL;DR T'Pol's character was wasted on a cast of dry characters offering no true juxtaposition of the way she mastered subtlety of humor similar to spock. If only the andorian would have joined the crew when it owed Archer one.
