Any sport will be boring unless the absolute best players are playing.
I can assure you, watching Lionel Messi is not boring.
A good English Premier League match or El Classico between Real Madrid and Barcelona is as good as any other sporting event you can think of.
Any sport will be boring unless the absolute best players are playing.I find lower-league soccer enjoyable to watch, too.
I think the problem is that it is an acquired taste. If you grew up watching soccer, you know about the subtleties of tactics and strategy. You understand what’s going on and can appreciate the moves of attack and defense. However, if you’re new to the game, you only see a bunch of guys running around for no apparent reason, apparently without achieving anything at all except a rare goal every half hour, with more useless running in between. Unfortunately, it is also quite hard to learn how soccer works by watching it on tv. You have to go to the stadium to see how the whole team cooperates, builds new formations, organizes attack and defense, until you’ll eventually get it.
Most grown-ups are probably not willing to invest this kind of effort. Which is a pity, because the reward is great indeed :-)
Baseball is just as much of an acquired taste. Well worth it, but it takes effort, too, to get into it if you didn’t grow up with it.
