I find games like that trash that Denver and Dallas played last Sunday mind numbingly boring because you know by the second quarter you're just killing time till the end of the game when the team who has the ball last will win. Lower scoring games place a premium on teams being good at all three phases of the game, and that's why I prefer them.
Like I said though, if I'm going to continue following football, I may as well start building up a tolerance for games like that. We're not too far off from a 34-31 game like UT played last weekend being the new "defensive struggle".
