Opinions will be divided on this.
Call of Duty 4 took simplicity to a new level, and this led to the fact that it was pretty much console FPS perfection.
Black Ops throws a lot of unnecessary content into the mix. It's not streamlined. It's pretty much full to bursting. And while there's no hacking, you know those irritating campers/grenade spammers/noobtubers from CoD4? Yeah, pretty much every match you'll play is full of them. And as a final nail in the coffin, if you're playing against anyone above level 30 and you've just started, you will lose.
Many, many people enjoy it. Millions of people. Personally, I detest it.
