Apart from the ridiculous sci-fi plot, and a rocky and obnoxious first few episodes, this drama is WAY overhated and underrated! I honestly think it's rated so low just because people have no patience for unrealistic plotlines and plot holes. When other aspects are done well, I can overlook something like this and it doesn't bother me too much.

I admit that JCW totally carries it which isn't a surprise, but the FL does a great job too and the romance aspect is enjoyable with really great chemistry as you would expect from these actors. I heard some say the romance came on too fast and felt unnatural, but it didn't seem that way to me at all. It was very obvious that the ML started caring for her out of feeling responsible for her health and whatever would happen to her as a result of the experiment he convinced her to do. And yes, this did start to develop gradually if you pay close attention. I did feel pretty bad for his ex though, talk about a crappy situation for her.

Overall I really enjoyed it! Then again I always love watching JCW just because of his acting style and detailed expressions, etc. which make him so great to watch... but even apart from that, it is a great romance.
