I thought this was one of the better episodes of series 5 actually. Yes, the pacing was a bit slower on this one (closer to classic who really) but I like that time was spent on getting to know the secondary characters.
Because of that I'm more likely to be emotionally invested in them than I was for, oh I don't know, the WWII space fighter pilots, or anybody from The Beast Below
episode. I think it'll pay off for part 2 next week.
