How bad is it? It's currently the lowest rated film on IMDB (1.5/10.0)
Should you see it? Hell no.
Some feel that the films being made by and marketed to evangelical fundamentalist Christians are the modern equivalent of the Commie-bashing films of the 1950's and will seem just as silly in time. I'm not so sure. What I am sure of is that no one will enjoy this film. The film's about a girl who devotes her life to dance and then finds out she has leukemia, so I expected an Afternoon Special type weepie with some dance sequences. Instead, the girl develops extrasensory powers with her cancer (if that's the big C of the title, I think that's unintentionally clever), which allows her to instantly convert people to her faith, stop suggestive lyrics in songs and remove nudity from film. For someone with cancer, she never gets sick and doesn't spend much time around doctors. She has a long argument with the devil that would be boring for a Sunday school lesson and when she finally - finally! - dies, she's clutching a license plate that reads "C ME DANC" The fact that it's not quite the same as the title is telling. This film has acting worse than the worst of high school plays, special effects that came with the camera and a plot and characters that are completely uninvolving and irritating.
