Mermaid double feature night:
Killer Mermaid (2014) - some young people go to an oceanside resort and spend a half hour going through some dull "romantic" (as in not romantic whatsoever) shenanigans. Things finally pick up when they go to an island that has an abandoned castle on it - a vicious serial killer lives there who feeds body parts to his killer mermaid. Pretty gory in parts, it managed to create a bit of suspense and the characters were okay. One of the girls was pretty darned hot
She Creature (2001) - back in the 1800's or thereabouts, some carnival operators in Ireland chance across a mermaid and load her (in her huge aquarium) in a ship bound for the New World. Turns out she can control people's minds though...not good for anyone involved. This had a decent plot and good characters. Also created some nice atmosphere, as most of it takes place aboard an old sailing ship. Special effects were good too with the Stan Winston Studio doing them. It did kind of run out of steam towards the end though; got a little slow and the climax lacked any real drama. 3.5/5.
