Sadly I'm the type of guy who can't stop watching something once he starts. After a friend told me to watch Hospital Playlist and my sleepy nocturnal brain started watching Hospital Ship on accident, I had to finish it. Sadly, I also watch one drama at a time, and because watching this drama felt like a drag, it took me ages to finish it.

The premise of the hospital ship is kinda cool, and the characters are very diverse and quickly everyone has a very distinct personality making for a fun group of individuals, making it seem fun at first.

Then you realize the "operation" bit every episode is awful, most of the actors either act poorly or got a poor script, and a lot of situations are just insanely timed that it becomes really unbelievable. I thought I could get through it with the eventual romance, but even that was very boring.

Ha Ji Won plays her character quite well, meanwhile Kang Min Hyuk plays the most boring guy with zero personality (He looks like a fun guy to be around IRL to be fair, but either his acting or his character are just unbearable). He gets a bit better towards the end but even then he's still a husk of a human being.
Lee Seo Won is actually quite enjoyable to watch, but he's got sexual assault charges these days so that makes it quite a bit harder to like him.
Kim In Shik and Mina play typical boring, below average intelligence characters who try to brighten the mood, and Lee Han Wi is simply unbearable.

I don't really know who the target audience for this show is. A lot of the show is cringe which makes me believe that it's aimed at 12 year olds but there's also a lot of blood and visual surgery which isn't that suited for children.

Would not recommend watching this one, unless you're a big Ha Ji Won fan or something.
