I enjoyed watching Doctor Stranger :)

Even though 20 episodes sounds a lot i was able to breeze through within 2 days. That tells me the story was captivating enough to keep me engaged (along with dramatic musical score). Its not without flaws though (especially the silly elements that occurred during the screenplay - you will notice someone roaming around unnoticed all the time)

I especially loved the ending, it's a satisfying and a happy end. Everything (main characters) ties up nicely in the end.

It may not be the best K-Drama out there but due to the low rating it may fly below people's radar. If you enjoy political thrillers, medical dramas or destined romance you should give this a watch.
