What theories and assumptions did you make about the film BEFORE watching the directors cut?

This question is for people who have seen the original version before the directors cut, since the original doesn't have the philosophy of time travel excerpts you wouldn't have been able to know about living receivers and artifacts and the like. So,what theories did you come up with watching the original (e.g Frank's identity,the weird gloopy things coming out of people's chests,how Donnie saved the world etc.)
