Bobby axelrod was always the main charector on this show to me. Then Damien Louis stepped away from the show. The only reason the other actor who plays mike prince became a co star was because Damien Louis stepped away from the show. He comes back for the final season and I see another reviewer talk about how they feel sorry for Mike prince and never mentions Bobby exelrod once even though him and Chuck basically are the show from the beginning. And Mike prince was only temporary upgraded to main charector to fill the space but they brought Damien Louis back for a reason because he is billions. Mike prince is not.
