Not much except Effects

Rating: 3/10 (7 March 2018)

There is nothing in the story, which (even if the Director has denied), is really a cross between Miranda (1948) - there too an amphibian (Mermaid in that case). Being of that age, there was no nudity, but the mermaid after being freed, did have a baby. And the rest is what is seen in ET or even the F4's silver surfer (the scientists on dissecting the alien, which the protagonists would try to thwart).
