They get every single aspect right.
Cast flawlessly, beautifully executed both on screen and behind the camera, and packed with moments of beauty and heartbreak and growth and friendship and heart pounding romance. If you watch no other dramas, watch this.
I would die for Fujisaki. Kurosawa's huge fragile heart destroys me. Adachi slowly waking up to the world is the very definition of hope. Seriously, this is the one. Look no further.
