Young Sheldon season 6 is doing a good job continuing the Coopers' narrative, but it's missing out on telling its best story, which is happening off-screen. After a chaotic Young Sheldon season 5 finale, Sheldon and his family are slowly settling back into their old routines. Mandy has moved in with Meemaw, which effectively makes her involved with Georgie's clan. Meanwhile, Sheldon continues his East Texas Tech adventures, while Mary and George work on their marriage. Amid these, there's one particular plot that's taking place simultaneously in the background that Young Sheldon isn't actively tackling and, The Big Bang Theory spin-off is missing out on capitalizing on it simply because it won't shine a light on this particular narrative.
In Young Sheldon season 6, episode 4, Missy comes home and rants about her adventures in school where she is once again dealing with stereotypical teenage experiences. Since Sheldon transferred out of Medford High School, and especially now that George is no longer working there, the comedy barely shows what the Cooper daughter's situation is at school. Tackling Missy's typical growing pains sounds fun and relatable, which could help Young Sheldon further broaden its reach beyond those who enjoyed The Big Bang Theory. Unfortunately, since CBS no longer films scenes at Medford High School, most of her experiences are now established via her narration.
Despite Missy's barely being in The Big Bang Theory, she immediately made a mark — something that the spin-off should be capitalizing more on. The Cooper daughter remains to be Young Sheldon's best character, and yet, she has been frequently relegated to a supporting player. Instead of tackling her own arc separate from the rest of her family, CBS opted to use her as emotional support to all of her struggling family members at the end of season 5.
As Young Sheldon breaks away from Big Bang Theory, it has gradually transformed into a family comedy rather than a straight-up comedy.
Given George's impending Young Sheldon death, CBS has a limited time window to diversify its storytelling before it becomes all about the Cooper patriarch's cheating scandal and demise. As established on The Big Bang Theory, he died when the twins are 14 years old, and they're currently 12 now on the comedy. This means that if they plan on giving Missy her due, it should start soon.
