It's a good show, but the popularity it had is not deserve imo, the show just mixes good drama and characters personality with a bit of cruel games that are not that good. What's your opinion about it?
I don't know if it "deserves" to be the most popular show in the world, but that rarely has to do with what's actually the best show. Netflix's last big hit was Tiger King, and that was a trashy mess. I'd much rather have everyone talking about a well written drama than another Tiger King.
