I really loved the moment when I could laugh but also moments when I cried my eyes off. The story was interesting but sometimes I was bored when the fighting scenes was up. It was sometimes too long but it was okay because storyline brought something new and entertaining after a few boring scenes . For me it is a series worthy to watch.
About cast in my opinion no one would be better for the characters. I really enjoyed the father son dynamic and also the not so romantic romantic relationship. You will feel like you are part of that weird group and that is another plus in this series.
