In the last couple of episodes I noticed that the stories are getting better it seems like since Billy Piper left the story lines are getting better the special effects might be 2009 but the stories remind of the classic series I could see Tom Baker Jon Pertwee or Peter Davison doing shows like these. That was back when content had more impact than special effects. A simple problem compounded by a bunch of outside problems, is how the show always worked best. If I do this how will it effect the time line, politics of the era, and always the creepy bastard that works for or betrays to the other side causing problems on top of the one that is there to begin with, its a good formula I think the writers should stick with. And above all let us learn something scientific and moral from the show.
The people that just started following the show in recent years may miss the outside problems he could be in big trouble some place for helping the Mars base but he breaks those rules knowing full well what the impact might be on the time line. He's faced with this problem through out the show, it reminds me so much of the classic stuff I felt an urge to watch genesis of the daleks. Its a good formula the old writers had and sometimes I think they still use. So lets take away the term classic in front of the older Doctor Who episodes and just call it Doctor Who all of it.
