Very well paced, but loses suspense a bit fast

Rating: 7/10 (8 October 2018)

This sort of film is quite difficult to accomplish because it needs to be seamless between the events and actions taking place, and the theory behind them. The film makers have to be extremely careful not to give away too much, too early in the film, and they also have to make sure the film doesn't come across as one big explanation of itself (à la Inception).
The introduction is poignant and catches the viewer's attention quite immediately. That momentum rides into the whole bulk of the film but then it turns slightly flat. Eventually we realize that "flat" area is essential to the very point and understanding of the film, and that's when we get into the crux of the plot. The movie starts to explain itself, and that happens a little fast in the film which makes it, not so much predictable (because it's not) but rather switches off the intensity and genuine sense of mystery that had been maintained so far. It's almost like film and viewer partner up together to see the story progress logically. The ending is interesting and offers yet another twist to the story and avoids a disappointing final impression and it's making a genuine statement rather than just trying to be a dramatic ending with no meaning, as often in this sort of twisty tale.
The film probably suffers from a bit of herky jerky laying out of the plot, which interrupts the suspense before sparking it again some more, and would've benefited perhaps from a different setup.
The setting and casting are good, the acting is good (from all, but Cusack in particular) and visually the film is rather memorable. I would give this about 7/10.
