Doesn't the very idea of this sequel, let-alone the trailer, miss the point of one of the most important elements that made the original so brilliant? In a reality so surreal that a jet engine can crash into your living room and the local self-esteem hero is a closet pedophile (two of many events), where obscurity is condemned but violation of the natural order of society seemed to come with rewards, how was a boy plagued with schizophrenia to distinguish the things that truly were real from the things that were a product of his mind/disease - how was a boy struggling with the idea of morality to determine right from wrong? Donnie's schizophrenia, which wouldn't likely be present in his younger sister (even if it is more probable than in the general public), was such a fundamental component that I don't see how they could replicate the idea in a sequel without blatantly creating a story that says, "I was designed for the sole purpose of being a sequel to a tremendously popular cult film." (That's not to say, of course, it couldn't have made a perfectly fine film independently - I fear that like Saw II or Hellraiser: Deader, for lack of better examples off the top of my head, it will be an otherwise intriguing story which finds its least redeeming qualities are the very things that solely exist to try to tie it to another movie/series.
Any one else agree/disagree?
