Superman had bad ratings for the last 4 seasons why do they get a chances? Smallville since after season6 has had viewers under 4 million and was kept on TV. Heroes had 4 million it's last season why was it not given another chance? I realize that Smallville was on the WB than CW but come on. This is BS Heroes should have at least been alowed to rap things up with a tv movie or miniseries. Public TV is so messed up right now.
