Stand By Me
The Alien series
The Species series
Take a little bit of each of those films and you have Dreamcatcher. A film classified as a horror is more of a Sci-Fi psychological thriller about a group of 4 friends who save a boy from physical bullying and they receive telepathic powers. 20 years later, an alien race is taking over earth and implanting their seeds, you'll generally know who's infected by a scar on their face. Not everybody dies and produces an alien child, some recover and return back to normal.
While, the film isn't original on its own. It has a lot of concept from 5 or more different films all chalked together. It's a departure from the general drama that plagues Steven King films, but it's got that coming-of-age element. Very little with some back scenes throughout the film is spent on the past sequences. The military in the film makes it feel action oriented.
