I saw Flashback. it was interesting more because everyone saw 6 months into the future. That's a pretty good premise to start out with because there are a lot of scenarios to work out. It will be fun to see if they can prevent some of the things they saw, death, divorce, returning to alcoholism, etc.
I have some trouble with watching doomsday movies because some of my family are still dubs and it winds them up too much. Puts them in dub mode way too much.
