Or more of a sense of adventure. As a fan, of course I'll take exploration of the show's mythology or delving into the psyche of the Doctor. But the average viewer wants to see fun adventure or they'll just flip the channel.
Yes, more adventure!! But I would love it too if there was a more consistent story arc that tied together the individual adventures. The Key of Time arc with the 4th Doctor is a good example of what I am talking about. Each episode was an adventure but there was a clear purpose that tied it all together. In fact, I thought we were going to get something like that with the Search for Gallifrey.
