Kingdom
The only reason why the thought of dropping it crossed my mind, was because it's animation were on the level of the new Berserk animation (2016/2017), basically, it sucked. For some reason though, I continued to watch it because some of my friends for a social site I use a lot, have kept saying great things about it so I endured until I've finished the first season, if you disregard it's horrible animation, it's actually a pretty ******* great series to enjoy and when you get to S2, the animation is beautiful.
I'm glad I didn't drop this because now, it's one of my top 10 series that I enjoy to this day which made me read the manga counterpart, and the manga counterpart speaks it's own story as well.
