Kevin Costner has had a number of critical flops to go alongside his more iconic successes, but the movie regarded by many as his worst ever, 2002’s Dragonfly, was born directly out of M. Night Shyamalan’s classic thriller The Sixth Sense. The supernatural thriller from director Tom Shadyac (Liar, Liar, Patch Adams) stars Costner as a doctor who is grieving the loss of his wife, who was seven months pregnant when she died in a landslide. His wife reaches him from beyond the grave through his patients that have near-death experiences, which ultimately leads to a brief supernatural reunion.
