Yes, I did like that aspect of it.I liked A Town Called Mercy. I've seen a lot of people draw parallels between what Amy told Eleven about killing and what Rose told Nine about destroying the Dalek in... well... Dalek, as well as Donna's reminder that The Doctor sometimes needs people to stop him. I like that that is a theme of sorts. The companions essentially help him hold onto his, I suppose, sense of humanity.
I totally understand why BK is so eager to see the Ponds leave. I am glad that we get to move onto another companion, but I'm just dreading actually seeing Rory and Amy leave the show. Once they're gone, I'll be super pumped for the new direction the show is taking, but at the moment I'm really apprehensive about HOW they're going to leave.
