This has to be one of the darkest and grimmest endings of all time...
***SPOILERS***
Two totally innocent kids have to experience devilish murder and mayhem in their childhood. So far, so bad.
Then: The boy spends the next ten years (!) in the looney bin because he technically shot his father but was in fact only trying to protect his sister from a demon spirit. NOBODY BELIEVES HIM, of course.
AND HOW DOES IT END? He technically kills his sister (but it was of course just another one of the mirror's satanic mind tricks) and probably gets the death penalty or life in prison or the rest of his life in the LOONEY BIN A G A I N!!!!!! AND NOBODY WILL BELIEVE HIM THIS TIME EITHER!!!
How *beep* UP is that for a person's fate??! I was sitting there really speechless for a minute during the end credits, only slowly comprehending what a pitch black and utter victory it was for the mirror...
