Time is linear. This movie is not. (spoilers)
When you have to check IMDB halfway thru a movie to figure out what is going on, there might be a problem with the editing.
There is no indication when you are seeing a flashback, or a flash forward. For a while I thought Cass was two different girls and the couple was unlucky enough to have 2 daughters abducted.
The flash forward to the office building wasn't even noticeable til you see the same posters at the banquet.
Then one minute the detective is locked in a van, then she's back on the case at the hotel.
I'm confused as hell....
