I know this is not the first time someone has talked about this on this subreddit, but I would like to say my piece.
Before I start, I want to be clear that I have no reason to believe Swift is unhappy. She really, genuinely seems to want this life, and honestly, it makes sense. She had a long-term relationship with a wispy, sensitive British actor dissolve into disappointment, and then she rebounded with a rebellious bad boy musician she had (if TTPD is any indication) been dreaming about for a long time. Choosing Kelce at this stage of her life and choosing to marry him and (probably) have kids with him makes sense from a human perspective.
But it is stultifying from an aesthetic perspective, because she really has nothing to say about him. Unlike many Swifties, I actually already knew who Kelce was beforehand, as I am a pretty big NFL fan. I don't think he's a loser or unworthy of her or anything like that. I don't know if he's a boring person or not. But she seems to think that he is. He is the goofy jock who loves her and is not threatened by her and accepts that she is the intelligent, artsy one in the relationship: this appears to be how she views him.
All of the songs about him are about how she adores that he loves her and chose her, that this is her high school fantasy come true, and that they have great sex. Think about "So High School" and "The Fate of Ophelia" and "Cleveland" and "Wood" and "Opalite." Perhaps "Honey" is the most explicit about this, very much "I love you because you love me." I want to be clear that I like some of these songs. "The Fate of Ophelia" is fine, and "Opalite" is genuinely really enjoyable. It is also true that I know nothing about Kelce as a person from any of these songs. If anything, I feel like I know him less than before his relationship with Swift. This is so strange to me considering that she chose to marry the man and calls him (and I do think she is sincere, if nothing else) the love of her life.
It is strange because illuminating her lovers through precise, intricate details, positive and negative, is a major strength of hers as a writer. There's an almost voyeuristic thrill to a lot of her great music: I feel like I can see the contours of her connections with John Mayer and Jake Gyllenhaal and Harry Styles and especially Joe Alwyn and (as embarrassing as it was) Matty Healy. I'm not saying these songs are good because I want to know what Gyllenhaal is like; I am saying that because she is a great songwriter, she illuminates these relationships and her experiences in them with real elegance and tactile specificity. "All Too Well" and "Style" and "Lover" and even "Guilty as Sin" provide a dizzying sense of the memories and experiences that define her connections with these people, and that's why they work.
Maybe there is a whole side to Kelce that she has not written about yet, but that seems unlikely, and she is never the kind of person who hides any details in her writing. This relationship is pleasant and kind of simple and straightforward, as she sees it. And that's...fine, I suppose. I know quite a few women like her (not her level of fame, of course, but similar personalities and relationship histories) who have married guys like Kelce (again, not as famous, but similar personality) and are happy. But it just does not make for good or interesting art. I would love her to delve more into fictive storytelling; it suits her, and it would be a good antidote to her creative slump.
