Based on the Rumiko Takahashi graphic novels?
Talking to a friend today and he mentioned he was watching The She Creature which I assumed was a remake of the 1956 movie of the same name
http://www.imdb.com/title/tt0050957/
But he started talking gibberish about mermaids and stuff so I looked it up.
Interesting.
Never knew it existed.
Any fans of the comic? How close is the movie, if at all?
