The Ending is....
Genius.
I love that ending, a lot of people complain about how it's a depressing ending & it's so downbeat & they were hoping for a happy ending. It's a horror film. They're suppose to be dramatic & haunting & that ending was perfect. The whole film had a cold & dark atmosphere & it kept it till the very end. You'd expect nothing less from a movie thats called 'Sinister'
Happy campy endings to horror films belong in the 80's & 90's, more horror films need more darker tones these days, I think Sinister is one of the more better horror films of the last decade, it does have it cliche horror moments but despite that I think its a great horror film.
If a horror movie makes you feel scared & uncomfortable & sticks with you long after the movie's over then it's done it's job & thats exactly what Sinister did for many viewers.
