Nothing overly original, but amusing on it's own way.

The Legend Of The Blue is that kind of drama you first watch and think: "I think I've seen something similar to that". After all this 'supernatural being meets everyday person' theme can be easily found anywhere, from eastern to western TV and movies. Also, it wasn't the first time the writer touched this subject, actually she did something similar with You Who Came From The Stars.

But even if not original, I liked it anyway. The Little Mermaid feels are strong on this one, and it's done on a very cute and emotional fashion. I also like the fact they basically told two stories at the same time and as the story progressed you could feel the links and similarities. The Joseon Era bits in the beginning gave a melodic, if not overtly fantastic feel for this show.

Ji Hyun once again amazes me with her acting. She's not afraid of being silly, not afraid of looking ugly or like a fool. The way she builds her character is genius. You can see that she's a naive, almost childlike mermaid who is totally new to everything, but being naive doesn't mean she's dumb, because she has her moments of quick thinking and overal awesomeness that gots you cheering and saying "you go girl". Also, it's funny to see her being the supernatural one this time, and starting to experience all kind of human emotions and feels.

Lee Min Ho is also really good here. I don't remember liking him this much in a drama since City Hunter. He makes a good character that is clearly sneaky and not trustworthy, that at the same time has a good heart and a cheery behaviour, he's not like those cold, emotionless peers we see left and right, which is refreshing. Other perfomances were also well done, I particularly liked Lee Hee Joon on this one, mostly because althought he looked perfectly normal and even cheerful on the outside, you never really knew what he was up to or which side he was really in.

Music is not really this drama strong point, but I liked it anyway.

I don't like to compare dramas at all, but I've noticed that the writer is not really good with handling villains. The one in The Legend of The Blue Sea and also the one from You Who Came From The Stars are...unidimmensional to say the least. They have no apparent reasons for being that, except for being "evil". And just being evil for the heck of it can be amusing, like in YWCFTS, but annoying like in TLOTBS.

Overall it's an interesting ride. Not as glorious as it tries to be, but still amusing on it's own right. Is it rewatchable? Yes, but not the kind you'll want to
