Cthulu
This is a modern take on the Lovecraft story - The Shadow Over Innsmouth, in which a guy stumbles upon a decrepit town of strange fishmen who worship ocean god Dagon. There's already a film called Dagon however so they had to go with his cousin Cthulu.
It's a first film written and directed by Dan Gildark and it's actually surprisingly ok if somewhat 90s music video towards the end.
Russell returns to his hometown after his mother dies and ends up staying for a while. His father is the (cult) leader of the local church and seems preoccupied with preparations. He runs into an old lover and finds a mysterious object as well as some mysterious fish men.
The most unusual thing about this film is the tender relationship between Russell and Mike. The strangest is Tori Spelling raping a gay guy.
NO - like recent Clive Barker movies but less terribly exquisite.
