For such a short drama, this one presented so many different questions and revelations and sex scenes...
For a drama called "Mermaid Story" it had surprisingly little to do with Mermaids.
However, it was an interesting drama and I did like it. The acting was pretty good, the story was okay (though odd in some spots), the pacing was a little off and the music was gorgeous. The music was one of my favourite parts. All instrumentals, heavy on the strings. Beautiful.
The romance was cheesy at best and, in parts, felt very forced. I wonder if that's because it was so short?
I don't think I would've stuck with this drama if it had been longer than four episodes because of the pacing.
Overall a 3/5 stars. I liked several of the actors, I liked the music and the story was fairly interesting. However, odd pacing, no mermaids and rushed romance prevents me from giving it a 5/5 star rating.
