An ending so awful you want to go and head butt a brick

Rating: 10/10 (6 October 2014)

*Big Spoilers*
I give it a 1 not because it this movie was dreadful from beginning to end but because it was engaging for most of it then the last half an hour was so unrealistic that the investment you make as a viewer to that point is completely trashed.
By early in the film (if not the trailer) it is apparent that Amy had been keeping a diary/journal of her marriage to Nick which went from fairytale to horror story over five years.
What is also really obvious is that the police do not have this diary at this point so will eventually find it and that it will incriminate Nick. So the obvious conclusion is that it is a set up.
That is not a bad thing as long as the story is well told and for the most part it was.
Several characters were of interest. Super lawyer Tanner Bolt comes in to help Nick with his case. Unfortunately that thread is a waste of time as Amy returning makes his involvement of no real service to the story.
Officer Jim Gilpin who was suspicious of Nick through the film could have been a more interesting character when confronted with new information simply remains a one dimensional character who therefore serves no significant purpose and was never intended to be a real person.
Toward the end when Amy comes back Nick is having a drink with his hotshot lawyer and the police officer who had been investigating her disappearance and tells them that Amy had confessed to him to murder (she had ripped a guys throat out) as well as having set him up.
No issue with that except the police officer says there is nothing she can do now and the lawyer makes a joke and leaves smiling while another police officer jokes that Elvis is leaving the state.
So for most of the movie we are given the impression that it is grounded in reality. Events that could happen.
Then to wrap it up the writer just gets lazy and creates a scenario that would never take place.
I have heard some say that the film is a statement on marriage but who cares. It still needs to be told within the framework or the rules for which the rest of the story has been set.
I read someone else say that it is OK to switch your brain off for a movie as long as that is established early in the film but not in the last half of an hour.
The ending ruined several story threads and made them pointless. If anyone seriously thinks the film was some serious commentary on the state of marriage then I think you are kidding yourself in the hope of convincing yourself that you are smarter than you are.
But even if it was no excuse for dropping the ball to get the story over with. I have no issue with Amy getting away with it or being convicted or being killed or whatever end the author chose but that needed to be done well.
Instead it ended in the laziest way imaginable and therefore ruined the time I had invested in watching the movie to that point.
I don't expect every film to be a winner but this dropped the ball so badly it is lucky to get the 1 out of 10 that I gave it.
