I finished watching the six episodes in a single day, so I don't think I need to tell you how gripping and addictive this first season is! I decided watching due to being a fan of Hyena, and I definitely wasn't disappointed. Hyena is my favourite K-Drama of all time, but maybe is now joined with Kingdom? Definitely a possibility.
Some characters were instantly likable or you at least had a serious connection with them throughout the story, however, I do believe one or two characters could have been expressed further, but considering I haven't watched the second season yet, I cannot criticise too much.
In a very weird description to describe Kingdom, I would say its a crossover between Walking Dead and Black Panther, with a Samurai twist! Which is obviously an amazing way to describe the show! P.S Kingdom is better than Walking dead, sorry haters.

If you like violence, zombies, gore, or anything within that region, this is a must watch!
