I've seen this show recommended by many sources. Finally I decided to watch it.
At first I was kinda disappointed. The first few episodes didn't make a huge impression on me. But as the story progressed and I got to know more and more fantastically written characters, the backstory started to unfold and alchemy expanded, it just got better and better.
At a point I suddenly found myself addicted to the show. When one episode finished, I immediately started playing the next.
The story deals with morally heavy themes. There is some seriously dark stuff in there. But there is also light. Once you experience terrible things in this show, it is truly cathartic to see some hearthwarmingly good things unfold as well.
This show will make you feel very deep feelings. I have to admit to be crying at some points. It is a true roller-coaster.
You will get so attached to the characters that after the series is over you will seriously miss them. That is a quality of a great show.
The scope of the story is bigger than anything I have ever seen before (no joking, the stakes are bigger than in any other fantasy / sci-fi).
You will find yourself truly rooting for the good guys, worrying about them, and cheering when they seem to succeed in combat against a foe.
If you want to be amazed, addicted, emotionally lifted, press the start button on this show.
