Or, if the Internet existed earlier, the JNT era which divided fans. Colin Baker, anyone?
I think the divide is now between those who want a companion-focused show or a Doctor-focused show. I am for the latter, for the show should be about him. I, also, liked that the people involved in the Classic Doctor Who put in unofficial guidelines about him - that we shouldn't learned much about his background (there should be a mystique about this alien), that he shouldn't "stoop" to our level, and that the companions are the conduit to the Doctor. (As some can tell, I am listening to the commentaries. Some of them are very informative. Others less so - hearing the actress playing Vicki saying that she doesn't remember much of her time on DW got old.)
When the show had serials that went for weeks, the most successful of them had struck the right amount of balance between the Doctor and the companions. (And, it was a plus when the writing and the directing was top-notch.)
The latest episodes are 45 minutes long, which means that there isn't the time to create a balance between the Doctor and the companion. The show has to go one way or the other.
I think the show is in a rut and that it's time for a major change from the top-down. The pattern was set in the 2005 season, when the companion became the focus of the franchise, there was a season-long arc, and the Doctor's existence was threatened. It's time to break the mold and do more experimentation. I think Doctor Who, as a space fantasy (Verity Lambert's words), is a flexible franchise where experimentation can occur. I was more intrigued by the adventures hinted at in the beginning of this episode, than the actual adventure in the episode itself.
The robots in the Classic Doctor Who were largely let down by a budget-tight BBC. Many drawings were marked with the words "omit" written on them because of the budget. If they had the budget of today, some of them might have been less rubbish. The robot in the current story failed because there were hints that this thing might have a fascinating story of its own to tell, but the writers choose not to tell it, resulting in a villian that was more MacGuffin.
How would I have written the episode? I would have it Doctor focused, with Clara and Danny as the companions on an adventure. The Doctor learns about the robot's mission and, with his companions, they confront the agency that sent the robot. During the adventure, the Doctor comes to respect and like Clara's boyfriend.
I would have dropped the balderdash about the Doctor being anti-soldier. Watching the older serials, I think he was more opposed to the mindset that prevented the military from seeing other options. The Doctor made friendships within UNIT, and developed friendships with other soldiers from other time periods.
