It was already entertaining in the trailer, and the whole drama is even more so. The story is great, and even the flashbacks weren't boring. The twists are unpredictable. I enjoyed watching even the minor characters. This is a hilariously funny and entertaining drama even though it's a fantasy. No boring episodes and the ending is really great.

Jun Ji Hyun really never failed to amaze me. She really made me laugh so hard. What I love the most is the fact that even some of her acts here are overly stupid (as expected from a mermaid who knows nothing about city life), she was able to play it well that it was still funny and not corny. I love her when she tried to imitate action scenes in the movie she has watched. I also enjoyed her fashion here.

Lee Min Ho is indeed handsome, but I found him more appealing and charming in this drama. I saw different styles of him here. He is really a great actor. He's so cute whenever he's hiding his reactions to some incidents. What I find most hilarious is when he set rules and curfew in his house. I can't forget the scene when he said to Shim Chung that some dress are bought just to be kept in the closet????? Every kind of role suited him. Whatever character it is, he was able to really play it well, and that's what made him so amazing.

All the actors and actresses here suited in the role they are playing. I love everyone. Oh, especially Jo Jung Suk, he really made this drama more hilarious. I love all the scenes he's in. My heart broke for what happened to him in the end??

This is really a must watch kdrama. It's also one of the best kdrama and a kdrama for beginners.
