Like the lighthouse....

...one can see the twist in the story miles away.
SI is slow boring and not as smart as some of the reviewers think it it is. This film is one more of those films that question sanity and whose main character (in this case Leonardo di Caprio) is found to be living in an alternate reality.
A person with half a brain would have seen that after the first 15 minutes.
Well, all SI does is to jump back and forth from "the realities" experienced by Di Caprio's character at the beat of a dreadful and annoying musical score (it gave me a head ache...). To make things worse it ends in an ambiguous way, another gimmick to make the viewer question his own reality... not very original.
SI tries hard to be a horror movie, to create an eerie atmosphere, to involve the spectator with a mystery and a drama that simply are not there. It fails poorly.
SI is another example that Hollywood has run out of original ideas.
