I only watched it all for the second time since it came out a couple of weeks back (I sort of fell off the Doctor Who bandwagon and have been getting back on. It was gradual, where first I just watched everything 1 time as it came out). I actually had to pace myself with some of the scenes – and it made me want to watch "Years and Years" that he produced or wrote given how dystopian and much more uncomfortable certain aspects of Children of Earth felt 10+ years later.
