It’s way too early to pass judgement on Peter Capaldi as the new Doctor, but I have to say…I thought “Deep Breath” was a step in a very interesting direction.
First of all, “Deep Breath” requires the viewer to have an understanding of the Doctor Who-niverse. It is a horrible episode to start watching this show on. This episode starts mid-conversation with people who have been having this conversation for about 50 years. So, if you watch this episode and are confused - it’s not just you. Go back a season or two and catch up.
