In general I'm not a soccer fan. I'll watch some World Cup and Euro matches, but general league play regardless of where it is I too nod off or drift to other more interesting things. And just about any household chore is more interesting. 
But. Caught the last 20 minutes of so of regulation and all of extra time in last night's game and it was riveting. The emotion from the crowd certainly helped. But the play was very unsoccerlike. Unpredictable, fantastic runs, close scoring opportunities. I liken it to college basketball. I'm not an NBA fan either - too predictable that they (almost) never miss, but college hoops has the passion and uncertainty that the pro game lacks. Ditto for the match last night. 
And watching any sport in horrific weather is always enjoyable!
