What the hell is Booker T doing as a commentator in SmackDown?

When Booker T returned to WWE he said he always wanted to be a commentator.Plus he didn't want to take away spotlight from younger guys by being a wrestler again.He'll be like Lawler be a commentator and maybe make a couple storyline/angle/matches.I don't get why people hate Booker as a commentator.I actually liked him as a commentator.Just be happy he's in WWE.I don't think he'll ever go back to TNA.Probably had the same problem that Nash complained about for TNA,the pay mostly.
