13. The Bye Bye Man
Why It's Terrible: Obviously, the movie's title is a pretty obvious clue-in that it's hot garbage, but make no mistake: The Bye Bye Man isn't just a dumb name.
A weird mash-up of numerous better horror flicks (perhaps most prominently A Nightmare on Elm Street and, more recently, It Follows), in its worst moments this is a howlingly bad unintentional comedy. What other movie this year can you hear a child ask their dad, "What do you think I am, a flashlight?”
Why It'll Be A Cult Classic: As if its accidentally campy qualities aren't enough, there are actually some relatively decent ideas here buried underneath all the slop, particularly that the antagonist can be conjured by the mere thought of him.
It's a good enough concept to make the movie a giggle for shlock-hounds, and the baffling supporting turns by Carrie-Anne Moss and Faye Dunaway only add to its innate strangeness. Above all else, it was much weirder and sillier than your average awful studio horror flick, so that's something.
