I used to enjoy it, at least when the Steelers are playing. Then I got into soccer, eventually getting a more expensive cable package to watch the Premier League.
Now when I watch football again, I am painfully aware of the time between plays, the incessant commercials, and now the ever increasing number of "official reviews". Seems like every 3rd or 4th play, an official has to leave the field, watch the play over and over and over and over again for 5 minutes, before announcing that, yes, they got the call right in the first place.
Soccer, the action flows pretty constantly, and it's all done in under 2 hours. Watching football is a grueling, four hour commitment. There goes your Sunday afternoon (and evening, if you are enough of a glutton to stick around for Sunday Night Football).
It's starting to all seem like Farmville. Something terribly boring, that somehow the general public has convinced itself is a lot of fun.
(But please don't tell anyone I said this, I live in Pittsburgh!)
