Unhinged is a hyperbole promoting a pacific statement. When in fact, all that mattered was the action. For me, that was an issue, the opening credit and the epilogue gave me the impression to watch a social issues ad on TV, the message is in your face and not bright at all.
Also, whoever hired the actors did a really poor job. Not only because the actors are all bad (except Russel Crowe), but because they don't fit together in terms of the age difference. The age gap between the actress playing the mother and the actor playing the son should have been greater, it bothered me for all the film.
