These whipper snappers. "2001: A Space Odyssey" ends with a half hour of nothing but special effects tuned for heroin users. 1999 (?) "Planet of the Apes" where Earth somehow became an Ape planet can only be a result of the director being drunk when he watched the 1968 version. And has been well documented in many places, the end of "Sixth Sense" implies that Bruce Willis walked, talked, went places, ate, and lived his life for months, seeing that he had no effect on the physical world, and did not realize that anything was wrong.

1999 (?) "Planet of the Apes" where Earth somehow became an Ape planet can only be a result of the director being drunk when he watched the 1968 version.

That is, in fact, the twist ending of Pierre Boulle's original novel (on which both movies were based). In the novel, the protagonists travel centuries into the future (due to time dilation) and find a planet inhabited by intelligent apes orbiting Betelgeuse. When they return to earth, they find the apes have taken over.

In the 2001 movie, the ending is much the same, except that Mark Wahlberg's character travels back in time to the movie's present, where the apes have, again, taken over. (Though why this should have happened is somewhat inexplicable.)
