So wait The Doctor risks everything and breaks all the laws of time to save Clara after she died , a girl he has known for 1 1/2 re-generations. But for River? His wife that he has known for three lifetimes? "Sorry River, some things can't be avoided" Really!? This would've come as a much better episode if it didn't…

God I'm so freaking tired of Clara. The doctor has had soooo many companions and each one "Is the best one ever that he really super cares about, the fact that this one dies is sooo important" It just got so annoying with Clara these last episodes.

It was nice and all that Killgrave died a pathetic death but I hated him so much in that last scene that I really wanted to see Jessica pop his head. We had so much bloody death in this show why couldn't we get one more for such a horrible creature as Killgrave?

I feel like rule number one for a show that has immortal characters should be to not reuse the same actors

This episode raised so many questions.
1. How does a newborn vampire baby bite with enough force to cause harm? We've seen no evidence that these vampires have fangs.
2. I'll bet money that even though the photographer and the models came back as ghosts, the ghost rule is going to be completely forgotten even though…

I call bullshit on the vampire boy being sent home without anyone realizing his body temperature was a good 20 degrees colder than it should have. I've never had pneumonia but I assume once you "miraculously" recover they check all your body vitals again to be sure

I hated this episode, its a shapeshifter episode so It will always inevitably end with "Oh character X was actually an Imposter all along" or "Oh wait no character X was actually the real person pretending to be an imposter all along."
