Rome is a two-face.
He will have on a great interview with a guest, and he can get them to open up and really share personal feelings and insights, I like that part of his show.
But then he will just rail on people. There's nothing wrong with having a little fun at someone else's expense, but he is just mean....not just poking fun, but maliciously attacking their character and making fun of their mishaps (e.g., the Carl Lewis national anthem, Jeff Gordon saying "Chicago Stadium" instead of Wrigley Field, Ashley Simpson's SB halftime show, etc.).
I admit I find myself laughing at many of his put-downs, but he doesn't do it in a Jay Leno "laughing with them, not at them" way, Rome is just cruel and spiteful.
