The first series of this show showed us a village in a time loop. Various things changed in each cycle, but paranoia and violence were consistent across all of them.
The show provided little in the way of explanations, answers or resolutions. It instead focussed on the violence and creepiness.
This series dials down the violence and the creepiness and focusses on providing answers and actually moving the plot forward.
I personally like this because it makes the whole thing a lot more coherent. I obtained both the first series and this series together and was able to watch them one after the other as a result. If I had watched the first series when it initially aired, I probably would not have cared enough about the show to keep track of a second season. But I am definitely glad that I watched this. Watching the first series without watching this just leaves you confused and wondering what the hell is going on. But as a combo they work surprisingly well.
