With Pain Killer Jane and Flash Gordon both fizzling badly as sci-fi shows, the only good shows on now are Dr. Who (marginally, if you are able to accept the changes to the Who-canon), Heroes (waiting for the new season with great anticipation), and The 4400. The latter has taken some serious bold moves in plotline that you don`t see in any shows today. It is seriously showing balls unlike PKJ and Flash. This season has really gotten good, especially with the changes to characters. Simply AWESOME!
