I'd heard one or two people complain about what had been left out; for a one minute trailer it referenced a lot, but still, that was only a fraction of the stuff we've seen over the last fifty years. And that's why I love this trailer; it reminds me just how vast Doctor Who really is. If that makes sense. Also: "Our future depends on one single moment of one impossible day." I'm probably over thinking this, but I assume that's a reference to the "moment". The one the Doctor used to end the Time War with.
