Really gripping thriller - and the plot keeps you guessing right until the reveal, but then, given all of the possible outcomes - all of the possible scenarios that could have led to the dead woman in the loft, I actually found the real one the least appealing! Kind of like a magic trick, I loved it right up until I discovered how it was done, and then it just seemed so boringly straightforward. When it jumped to '1 year later' (which, as an aside, was unnecessary imo), I was still hoping there'd be one last twist that would continue the intrigue, but alas, it didn't happen.

That said, overall well worth watching, and quite unique I think. Anyone have any suggestions of similar flicks? Also, how does the remake compare?
