Fredp, Jim Caviezel is a better actor than you give him credit for. (You can even find plenty of photos of him smiling!) It's his character that is portrayed as being robotic. But we know his dispassion is just a shield -- after all he and Shaw were trained as killer machines by the U.S. government -- and now the government is forced to confront what a true machine killer is. Very subtle but effective, IMHO. As far as Root is concerned, she is very complex, and her character is beginning to be developed in an intriguing way. I wouldn't give up on this show by a long shot.
