John Cho is seriously an underrated actor. I've been thinking about everything I've ever seen him in and he is always able to fully become his character. Like Sleep Hollow?? Just started Cowboy Bebop and I already love his acting. (Sidenote never saw manga or anime.)
I'm repeating myself: Heaven Sent is one of those episodes that opens your eyes to the fact that you are watching and experiencing a work of art. Every piece had to fall into place or it wouldn't have worked. It really is a triumph
