A Town Called Mercy (Doctor Who 7.3)

I don't know if it's just because I'm a bit 'ugh' at the moment (some stressful stuff has been happening which I'm not going into in an open post) but I was actually *bored* this evening. I've been really enjoying having new Doctor Who to look forward to the last couple of weeks, but this felt like a real let-down. It just felt really... understated? None of the characters made me feel anything for them, except Rory, a bit. As I said, this could be just me finding it hard to feel excited about anything at the moment, but this is the first time I've been bored during the *first* airing of a DW episode in a very long time!
