The only two things that Philip K. Dick’s short story The Golden Man has in common with the film Next are the main character’s name and his ability to see into his future. This bodes well for my comparison!
In the story, Cris Johnson is 18 years old and has been hidden by his family all his life for fear the Government would take him away. In this future, there are people with a variety of mutations (think X-Men) who are feared, rounded up and eliminated. Cris has never spoken, he is golden and looks like a statue of a god. His ability allows him to see into the future, to all of the outcomes of his actions and all the different paths he could take.
