This is actually a nice movie.

I love how the small details of him being a mermaid and the value of his tears, blood and soul and that secret connects to the story flow and the ending. Even though the latter part of the movie was a bit hasty, and lots of holes in the plot, I pretty much enjoyed it. Could've been appreciated more if they made this into a mini series with 20 mins or less per episode instead of an hour long movie. Anyway, still a good watch if you just won't expect that much and appreciate it more.
