Not trying to be argumentative, but have you watched a complete game (may take more than one) where you actually cared what team won? It's possible having a "rooting interest" may help make the game more interesting.
My family (myself, DW, mom and dad before he passed away) came to realize how exciting soccer is by watching the kids play. My mom even told me today she watched the first half of the Qatar game today. Before our kids started playing, I couldn't watch 5 minutes of a match.
For me, baseball is an EXTREMELY boring game to watch. But talk to a fan who just watched a 1-0 game through 9 innings... same thing.
