This one has a special place in my heart because it's the only kdrama I've ever seen that shocked me into silence... multiple times...

at least half a dozen times I had to stop watching to emotionally process what I had seen just to remind myself that it was acted and that it wasn't real. Yang Se Jong plays 3 different characters: a set of clones and a doctor, and his acting never fails across the entire series.

The main scenes that I find the most memorable include the first fight between the clones which was incredibly done and the effects for that were the best I had seen in any kdrama ever. They were subtle, but my god they were SO GOOD!

The other one was the final scene with the doctor where he was vivisected... This is the reason I couldn't raise the re-watch value any higher because this scene felt far too real to me. I know that's the point but it felt illegal to watch that and I couldn't bare to watch that scene again even if i did watch the series again.

I noticed that there were a lot of kidnappings, rescues, and torture scenes--more than realistically i think there would be if this actually happened but I wont complain because the series overall was a great watch! :D

take out the final vivisection of the doctor and I'd watch it every year!
