Strange and confusing rules - but this is nothing surprising, the games developed slowly and the rules changed for a long time. But this is true for any game, take chess for example. The rules seem confusing to you just because you have not watched this game since childhood. The best way to understand the rules is to go to a game with someone who knows the rules well, take this person's word with great pleasure to comment on the game for you.
What about the fact that it's boring, first of all subjectively. Secondly: for Americans, the game is just a way of spending their leisure time, the game is especially slow for you had time to go for beer and hamburgers and did not miss anything special in 10 minutes.
Whether or not you are really interested in this sport is largely irrelevant.
A lot of the things we grow up are funny / interesting / enjoyable because they are nostalgic and bring fond memories. It's the same with food - you can't make an American understand your joy of borscht or piroshki, but also, I can't make you understand and enjoy spam sandwiches. These are cultural fads. Languages are another example. I studied Russian, but I will probably never deeply understand slang and cultural connotations and layers of language history. This will take many years of life in Russia. The same applies to you with English.
Because you do not give yourself the trouble to understand them at least at the initial level. You are so lazy that you did not include golf or croquet. Or handball. You don’t care about anything other than national existence (as if the jumping of representatives of northern peoples in height would be awesome, what a simple, understandable and close to everyone sport - and there was once an all-Union championship!)
