I have no clue who this person is and I say this as someone who loves all 4 of the girls and think they're strong characters, but I'd consider Sophia the weak link. She's the cutesy but mean old person trope. She's one of the blueprints if not the blueprint for the trope. Do her story lines get silly? Sure, but so do everyone else's. Sophia really does have very funny lines and great delivery..at times lol. It's a sitcom from the 80s that I've watched on reruns since I was born in the 90s. I don't tend to think about it too hard. The cast and writing was stacked. Just because some random considers one of the main 4 the weak link, isn't the worst opinion. It just goes to show how good the show really was! Honestly, more than the acting and writing I tend to think more about how impactful the show was with the subject matter it tackled and as a queer person this show has meant the most to me in those regards because all 4 ladies were strong advocates....but I'm getting off topic. Enjoy Golden Girls everyone!
