Funny you should mention the World Cup. I started off heavily biased against it (because Qatar) but ended up about as entertained as it’s possible to be by a football tournament. Would struggle to think of any other cup final I’ve ever enjoyed more as a neutral. In any competition. All of which goes against your notion that football as a spectacle has died a death.
I definitely find club football harder to enjoy but that’s mainly because of how much I despise the best teams around right now. Which is mainly a long term hatred that goes beyond any current jealousy. A football world where Liverpool, City and Arsenal are the best teams around is not really a world I want to partake in (obviously doesn’t help that Saudi owned Newcastle are coming up the rails). If we’re honest with ourselves I’d say this is a much more relevant reason for football being such a miserable experience these last few years than any lack of flair or skill on the pitch.
Conversely, I don’t hate Brighton and I enjoy watching them play (against anyone other than us anyway)
The world cup passed me by and I was baffled by how many people seemed to think it was the best ever. I enjoyed the final immensely but I couldn't point to any other game or moment outside of that. The thing that provoked the most interest from me aside from that was Southgate subbing on fecking Sterling for Saka.
...but then this is partly what I'm trying to gauge....whether it is just me who feels like this or a general trend. As opposed to proclaiming football has died a death, which isn't what I have said.
I would have thought despising teams would give greater incentive to watch games tbh. I used to watch every Arsenal game during the Wenger days because I thought they were a bunch of twats so would route for the opposition. Same with Chelsea, Liverpool, City, Leeds, whoever Robbie Keane was playing for...the problem is I don't feel that way about any team now.
United not being relevant to the top of the table is definitely a factor, but I think as much if not more so is that no one is really relevant because City have made it so no one can compete with them, at the same time as diminishing their own achievements by financially cheating in order to do so, which kind of renders the whole thing a bit pointless. Like a 400m sprint but where one person starts at the 200m mark and then we're all supposed to try to beat them and for some reason pretend this wasn't a factor when they manage to easily win. I don't dislike or like City. They are just there. I can't think of a single player I actively despise for on pitch reasons, at any club. But there's no getting away from it being less interesting when you already know who is going to win.
I think that's also part of a bigger factor that ruins my enjoyment which is the lack of integrity of the whole thing. Referees deciding games to help out their mates and using VAR as an incompetence enabler, pretending your players have covid to cancel games you don't want to play yet, or I've realised mostly the near constant diving and injury feigning in every single game (and this really is a big one because watching people pretend to be hurt over and over for 2 hours is really fecking dumb and boring). These things have been part of football for a long time but have also gotten progressively more prominent over time.
I don't think its down to one thing basically. Football just used to be more fun imo, and I used to have more time to spare to not be picky about what I spend it on.
