Adolescence
This is one of, if not, the best piece of television I've ever seen. I think what makes it so hard hitting is the fact that it's true all over the world, this isn't just a made up story. Our younger generations are seeing things without anything being regulated.
Obviously the acting all around is superb and the writing is fantastic as well. The whole series being filmed in one shot brings an extra intensity to it. My heart was in my mouth all throughout the series and at times it was hard to watch. This and the cast deserve all the the awards it gets.
