The first episode provides necessary exposition, military school, college, cute romances etc. Knowing that the age of the stars is around 40, this was a stretch and a little grating but I imagine that as the series progresses, this will become less of a problem. The show exhibits a somewhat different aesthetic than I am used to, it's very crisp but it does look like TV. It's long too, are all K-Drama episode 65 minutes long? I think it's interesting that shows only go on for one season, I like that format, the stakes are just gonna be higher, I hope.
I want to see some other K-Dramas too before I make up my mind about them, I know there are some that are meant to be very good. Iris just seemed like an easy introduction, it features a few stars I know (Lee Byung-hun, Jeong Joon-ho) and it's full of action/spy/thriller elements.
I'm curious to see where this goes.
