It all has to do with presentation. Everything does.
It's not that we have short attention spans, it's that "modern" is boring. Look at most of your Oscar-winning movies, downright boring with depressing asf endings that bring no joy. The best movie in a decade (Everything Everywhere All At Once) probably won't even be nominated because the movie is genuinely fun to watch. Modern music, so low energy. If I have to listen to Billie Eilish whisper lyrics about committing suicide to depressing background music one more time in my life, I will yeet myself through a window.
There's a reason Marvel movies are so successful, and it's not because of CGI and stunts. It's because the formula works. They're upbeat, sometimes funny, movies that bring you joy to watch. As stupid as these movies are, I actually sat down and watched a bunch of them during the COVID lockdown because it was a nice, HAPPY distraction.
Music from the 90s is the most popular music right now. The music of the 90s was very diverse, catchy, upbeat, high energy, and even the worst 90s songs are better than the majority of the crap being played on the radio (or is it Spotify now?) today. That's not even nostalgia because young people who weren't around in the 90s are jamming to this. When I was doing a bit of DJing during COVID, the 90s music I played was usually the most effective at getting people up and dancing.
As much as it makes TV snobs cringe to this day, "Full House" is still timeless television because it's fun and high energy and upbeat. But it's not "sophisticated" or doesn't "have meaning" or doesn't preach some kind of political message, so it's obviously crap TV.
This has nothing to do with attention spans, and Hailie's beliefs are disconnected from the majority of her generation. She has the right to speak her mind, and I have the right to say she's wrong.
NASCAR has a good product right now, and it has captivating personalities for the first time in a long time. People just have to give it time to blossom. And, for the love of God, find a TV partner that doesn't treat the sport like a damn cartoon, figuratively and literally. Fox Sports has been a problem for a long time. And it's not just NASCAR. NFL fans, by and large, have more favorable opinions of NBC and CBS. Golf fans loathe and detest Fox Sports. Baseball fans complain every October about Fox Sports.
