Having been a teenager in the 80s I remember the horror and shear terror of the accident, the fear and worry that the world we knew was going to change for the worse. The little bit of info which we did get was pants the rest speculation. This show had built in the fear, misinformation, gut wrenching, political wrangling ass covering, perfectly. The fact its a true event dramatised doesn't take away the horror you feel as you watch. It's flipping brilliant.
