I also was obsessed with this show when I first binge-watched the first season. Without Spoiling anything, The 2nd season is much more tense I would say as the people in the town have a much harder time. That season ends with a good cliffhanger and pretty much more questions mainly. In the 3rd and 4th season, things slow down and they start finding some answers slowly. I still enjoy it especially on a 1 episode a week schedule, but I'm no longer as obsessed as early in the show when there were so many questions. I look forward to the 5th and final season where everything will come to a conclusion.

Enjoy all the episodes you still have to watch!
