I have loved all the other series by these writers - all the Reply series and Prison Playbook. I really just expected.....more...from this story. It felt incomplete at the end -- I'm sure it's because they've set up a second season, but that is not why I watch Korean drama. I want a complete story.

The acting from the main cast was top notch - Jo Jung Suk is always a treat to watch as is Jung Kyung Ho. They did an excellent job, as did the others - no complaints at all for the acting. It was fantastic.

The music - from the band was a nice touch, but was a really strange addition to the story. It just seemed like some random thing thrown in even though it was fun.

There really didn't seem to be a real plot line, but just a bunch of stories about a group of friends who happen to work in a hospital. I did love the friendship between the characters and that was probably the show's strong suit and what I think these writers do very well. There were lots of loose ends that I wanted to see tied up that were left undone, hopefully that will be resolved next season. I'll end up having to read a bunch of recaps (because I don't have time to watch the whole thing over again) to refresh myself on what happened.

Anyway, I didn't hate the show - I enjoyed it but am bummed that it didn't feel completed. And I'll have to admit that towards the end, the excitement started to fade for it - like it was fine to wait several days to watch the newest episode.
(Sorry for all those that gave this a 10/10 - I wanted to love this and maybe I'll love it more when it's finished.)
