As I start this week's episode, the recap segments reminded me of something dumb with Saru.
His ganglia things fall out and he decrees of his species "our whole worldview is a lie"
Buh-wha?
How does he know that this is some newfound natural or evolutionary reason for what happened to him? For all he knows it was the crazy radiation of that big memory planet ball-thing that caused some sort of rapid mutation in him. Or he's an aberrant mutation of his species, like a birth defect or something.
I mean, the equivalent is if someone gets cracked on the head and suffers brain damage that leads to them becoming emotionless and suddenly people just go "Welp, I guess humans are evolving beyond the need for emotion now. Everyone go and be monsters without restraint!"
Granted we're supposed to suspect that what Saru believes (the Kelpians' alleged death cycle isn't fatal and if they stick it out they end up fine in the aftermath) is the actual and proper explanation for what happened, what the **** kind of scientist would take one solitary data point with any number of additional variables in play and go "yeah, that's a pattern. Behold the new normal!"
Also while I'm still like only 15-20 minutes in, I don't like the concept that this "new" Saru is permanent. Making him a 'man without fear' type who's going to be angry and badgering about his people and taking a distinctly humanist worldview is lazy*. It makes him no different than the crusader-like aspect of Burnham. I kinda liked that his skittishness made him a sensible voice of reason among the command officers and the right kind of "I don't think that's a good idea, Michael" foil for Burnham. It feels like they sold that out for the sake of this social revolution subplot with his people which could've played out just fine even with the old Saru.
*Saru's extended rant about the problems of his society and how backwards it is strikes me as an odd inversion from what we usually got with prominent alien cast members who usually either fully embraced their heritage and its juxtaposition with dominant human culture (Worf being the most prominent example), or who embraced elements of broader galactic culture while still retaining significant affection and allegiance to their original culture but also generally showed that their adaptability was inherent in their original characterizations (Quark and Rom, for example, frequently show that they were predisposed to non-traditional thoughts or reactions vs Ferangi society, but at the same time they also continue to value portions of Ferangi culture even after being "civilized", even continuing to embrace the elements of said culture that their new companions found backwards or unpalatable. Even in Quark's eventual acceptance of gender progress on his planet, a) It's almost entirely tied directly to him via his mother, which would seem to make a significant difference in his willingness to accept the change and b) he still resists it and remains linked to the ideals that were ingrained in him for his entire life, taking time and effort to adjust and make peace with his own tolerance for that sort of social upheaval before he reaches a point of being OK with it.). Saru gets one big soapboxy moment to shake the foundation of his cultural view of his peoples' place in the universe and he just goes full-on "this is wrong and bad" for little reason other than it would strike the viewer as wrong and bad and it behooves him to appeal to the viewing audiences socio-cultural leanings.
EDIT: yep, we're doubling down on this. "Evolved" Kelpians vs "Unevolved" ones. And then the nonsensical assertion that the Ba'ul (or however it's spelled) were once hte "prey" species? So say the two physicists and whatever the hell Airiam is. Because **** needing a sociologist or an evolutionary biologist to explain any of this to them.
EDIT 2: In total fairness to everything I ranted above, I don't have an issue with the plotline of the episode on the whole. I don't dislike the story that Saru finds out the truth of his people's history and the lies about their history and social structure. I just dislike that Saru magically reaches this conclusion based on his personal experience with no real external input.
I also dislike that Discovery participates in rejiggering the social structure and balance of their whole homeworld. I get that techincally the Ba'ul are a post-warp society and not bound by the Prime Directive (sorry, "General Order One" because we're afraid of that term for some reason), but jesus this seems like a huge amount of social meddling on an evolved and sentient species that they're totally OK with for whatever reason.
