Basically Final Destination with a Demon

Although the deaths are nowhere near as creative (albeit more realistic), this is basically a Final Destination film. A group of young adults finds out that they're destined to die in a certain order due to supernatural means, and along the way, they find out that there's a way to stop it. They stop it, but guess what? The final few minutes of the film reveal that it couldn't be stopped after all, and everyone dies. The basic premise is exactly the same, and I am fairly certain that the idea was probably borrowed. It's a decent film for a low-budget horror film, though.
