We (the whole family) went to see the Dodgers when we were in the US a few years back and surprisingly all found it quite dull (and my eldest son is a sports journalist and loves American sport).
I'm glad that we went but I wouldn't be desperate to go again or say that you'll love it. It is worth seeing as a traditional US pastime, but not much more than that. And it goes on......
Probably exactly like an American going to a cricket match!
