Okay, someone mentioned Iron Man similarities/references before. How about Stephen King references?
1. The GBO lasts for two minutes, seventeen seconds. In The Shining, Room 217 is one of the most haunted and dangerous parts of the book.
2. The phenomenon called "the shining" is in part pre-cognition (seeing the future), possibly as a message sent by a future version of the main character. The flashforwards are versions of the future.
3. The titles of both works (The Shining and FlashForward) are taken from these pre-cogntion events.
4. In both The Shining and FlashForward, not everything seen comes to pass.
5. In both works, the adult, male main character is a recovering alcholic driven back to alcohol as the story progresses, assuming Mark's flashforward comes to pass.
6. In Firestarter, the young girl is named Charlie. In FlashForward, the young girl is named Charlie.
