First of all, I agree that last year's was one of the worst ever.
This year's was poorly-played (and poorly-umpired), but at least it was close. That alone makes it better than last year's.
As for why I wasn't too interested in the series, it was because I didn't find either of the teams likable at all.
The White Sox were the most annoying team in the league all year because the media spent every waking hour (when they weren't talking Yanks-Sox) slurping at Ozzie Guillen's behind and giving them credit for things they did wrong. I was afraid that if they won, every team would be trying Ozzieball next year--how could I root for a team that would set baseball back 15 years? And of course, Ozzie certainly appears to be a certified douchebag off the field, so that's pretty hard to root for.
As for the 'Stros, they were more likable, but they had an anemic offense carried by Clemens and Petitte, who I don't care for (I'm leaving out Oswalt, of course, but I don't have much of an opinion on him). Petitte isn't really all that bad--just tainted by the Yankee stigma--but Clemens is probably a bigger jerk than Ozzie is, and it's awfully hard to root for him to pick up another ring.
When neither team is particularly likable, it's hard to get an interest in the series. In the end, I went for Houston just for Biggio and Bagwell's sake (and because the umpires got me mad at the Sox), but it wasn't exactly a vehement rooting interest.
For the record, I felt the same about Red Sox/Yankees last year. I only started watching when the comeback began, because I couldn't root for either of them. I guess I was the outlier there, though.
