I like it how emotionally doh kyungsoo deliver the message and the feelings. I really love his rich facial expressions. He's beating the "idol actor can't act" allegations. Also other actors like kim hee ae and sol kyung gyu acting are no joke! I also love the plot where you can laugh and cry at the same time. I dont wanna talk bout the CGI and cinematography, cause we all know korea's are the best at it. And the feel while i watch this movie is like i'm surviving too with hwang sun woo. It's a must watch and i recommend you to watch at 4DX for more realistic and super fun experience! Also it's safe to watch with the child and they'll like it too!
