"Show Sophie is so much more serious, less cheerful and optimistic, and frustratingly evasive and closed off compared to Book Sophie-"
Yes, and isn't that absolutely wonderful?!
It makes her more relatable to many of us anxious introverts who have always been serious, prone to worrying, cynically yet self-protectively guarded, and resistant to change.
It means that the moments when Sophie IS joyful and carefree feel far more poignant and meaningful.
Sophie hesitating to allow herself to feel and experience pleasure while Benedict is a reforming hedonist who indulged in too many of life's sensory, temporary pleasures at the expense of substance, depth and dealing with reality is one of many reasons that Benophie are so complementary and perfect together.
Being overly cautious, anxiety-driven and joy-deficient is a much more realistic response to her childhood trauma and current circumstances than "sunny" (Julia Quinn uses that adjective frequently!) Book Sophie was allowed to exhibit.
Making Sophie more somber initially not only gives her more of an arc as she learns to let herself be happy and open herself up to change and new experiences, but it makes her distinct from her altar ego, The Lady in Silver. The whole point of The Lady in Silver is that it allows Sophie to be someone significantly different from who she'd always been - not just by posing as someone who had greater status and freedom and a nicer dress, but someone who was HAPPY. And allowing herself to playact someone so joyful showed her that her real self was capable of feeling that way too. Plus, as people smarter than I am pointed out, Benedict's arc revolves around realizing that he wants something deep and meaningful and complicated and sometimes difficult but entirely real with layered, serious, secretive and harder to truly know Sophie rather than just an easy, pleasurable fantasy with the seemingly perfect Lady in Silver.
Confession time: While reading the series, I was in the camp who felt that the more perky princess Book Sophie came across as too perfect to be a multidimensional, relatable and realistic character. But the show compelled me to do a total 180, pivoting from "eh, she's as Mary Sue-ish as people claim" to "wow, she's not only among the most layered characters of the entire series but one of my favorite female characters ever!" No longer a perky princess, Show Sophie is allowed to be somber, cautious, secretive, too repressed to be honest with herself (let alone others!), and so phobic of change that she can come across as passive and remains "stuck" in sub-mediocre circumstances rather than proactively seizing control of her own life and being brave enough to change it. It makes her more relatable and more interesting - and makes her ultimate 'happy ending' vastly more rewarding!
