Yeah, this episode left a kind of bitter taste in my mouth. I liked how it showcased Amy and Rory and their conflict that their double lives place on them, and how its leading up to their inevitable departure we all know is coming (;_;), but the resolution was wayyyy too quick, especially for an antagonist we know absolutely nothing about.
Maybe much later in the show it'll all make sense, since that's what tends to happen, but at the end of the episode I was just thinking to myself "that's it?" and was pretty disappointed.
In any case, anyone who didn't like the Asylum of the Daleks is dumb!!! So there!
EDIT: What's really getting at me this season is that there really doesn't seem to be too much connecting the episodes so far. I mean, I guess looking at the Doctor's changing morality (killing Solomon wtf?) and almost sending the doctor to the slaughter in A Town Called Mercy seems very off, so I'm guessing this will become a factor soon too? IDK, the last three episodes have just seemed so random.
