This is about a man whom thinks someone is living in the big house with him he used to share with his ex-girlfriend. Is there someone living with him? Or is he simply going crazy?
Towards the middle of the movie it takes a twist you didn't expect and you're wondering where it's going till the end.
The best part about this movie is the ending because you have no idea how to interpret it. I LOVE those movies. Like Inception was the top continuously spinning or was it about to topple over?
Why this hasn't been remade for American audiences is beyond me.
If you don't mind subtitles go to Netflix and check this out. You won't be disappointed.
