Everybody hates the BCS because the very idea of a difinitive national championship in college football is ludicrous. There are too many teams and there is no opportunity to compare one to another in any meaningful way. They can't play a twenty game schedule followed by playoffs, which would be what is needed to have the matter decided by victories on the field.
The old regional bowl system had a lot more going for it, IMHO. I used to care who won the Rose Bowl, and this year, I don't even know who's in the Rose Bowl. Not only is the BCS stupid, it has destroyed whatever of beauty and value existed before it.
