Mermaid, Lake of the Dead
Kissmate is sick and running a 103 degree temperature, so (a) thoughts are appreciated, (b) we might have to go to urgent care if Advil and water don't bring the fever down, and (c) he wants me to live tweet a terrible Amazon movie to take his mind off the probable flu he has. [Editor's Note: This was previously posted on Twitter; Kissmate is fine now.]
This one he picked out: it's called MERMAID LAKE OF THE DEAD. It's on Amazon Prime. "For years, she has lurked in the depths, waiting. Once a young woman sent to a tragic and watery grave, she has since become something unholy. Cursed to swim the waters in which she met her untimely death, the mermaid has risen once again."
A little girl is explaining that the Russian mermaid in the lake will drown you as soon as you express your love for her and I'm excitedly screaming because it's a rusalka??? The little girl says if you DON'T love her, she'll hound you to your grave and separate you from all your loved ones. There's an escape clause if you give the mermaid your most precious possession, but nobody has ever managed to be released before.
On a bridge, a girl approaches a boy who has creepy blood red eyes. He falls into the water and she whispers "no, take me!" Then she manages to pull him out. OH NO ETHEREAL SINGING AND WOOD CREAKING. The girl just got yanked into the water by magic and blue hands before a title dropped. That was legitimately terrifying?
