I think you could say the same thing about any sport, depending on ones childhood experience.
I’m still far from understanding soccer enough not to be bored by it (with the exception of World Cup because of the immensity of the event), and annoyed by the constant flopping. Even though I know baseball well, I have no interest in it except maybe the World Series, and even then it doesn’t matter if I miss most of the game. But others could make the same argument about basketball or football.
Tennis is one of the most challenging sports, because aside from basketball, no other sport requires as many skills, combining speed, endurance, agility, fine motor precision, hand eye coordination, and placing a ball within a specified three-dimensional space. From a mental toughness standpoint, no other sport except boxing requires a player to figure out the tactics and strategy without a coach or teammates, while reacting to an opponent who is doing everything they can to hinder you.
