I would also give this movie 3.5/5 if the option existed. The concept and execution of the story is done well enough but the pacing of the movie is quiet slow.
It is a story that needs more awareness; that often the victims of these crimes can suffer and fall into situations where they are seen as the perps. Hugh Jackman gives an expected phenomenal performance, and is well supported by Jake Gyllenhaal and other well known actors who play their roles convincingly.
There are some reasonably significant plot holes and slow pacing issues that stop it from overall being a great movie instead of just a good one.
