Moffat is quitting Doctor Who... That's going to change everything. 

Not entirely sure if that's good of bad news.

Another weeping angel related plot hole! Weeping Angels seem to be like a magnet for plot holes.

Weeping angels can move incredibly fast.  In Blink, we saw that they scaled a building in moments.  In many other episodes we see that they can move from far away place to wherever the Doctor/main characters place in the blink of an eye.

Yet when they are close to the heroes, they only move one foot per blink.  Why not just run forward the next time they blink and send them back in time/kill them.

Doesn't make sense!!!
