CARJACKED: to car wreck by story's end

It's almost mind boggling.
The opening titles for CARJACKED credit no less than six production companies and eighteen (yes 18!) producers yet not one of them noticed that the final third of the film is absolute nonsense.
Not the kind of nonsense that only a veteran film reviewer with a pedantic eye would notice. I'm talking the kind of nonsense that is so blatant, so ridiculous, so... so.. so nonsensical that it will have you literally shouting at the screen.

Which is kind of a shame because up until this final third CARJACKED was squaring up to be a pretty reasonable thriller in a direct-to-video kind of way.
Maria Bello stars as Lorraine, a harrassed and impoverished single mom, who is carjacked when she stops at a gas station with her young son Chad. Stephen Dorff is Roy, the roguishly charming and violent bank robber who orders Lorraine to drive several hundred miles through the night to a rendezvous with a confederate. A cat and mouse gave develops inside the claustrophobic confines of the car with Lorraine looking for any opportunity to get herself and Chad to safety.
There's nothing particularly original here - of course there has to be a moment when she talks to a police officer searching for Roy but can't tell him what's happening - but Bello and Dorff are experienced and talented enough to create a believable relationship out of a script which is average at best.
But they are powerless to salvage anything resembling credibility from the grand climax with a twist which sees Lorraine transformed into a halfwitted Thelma and Louise and Roy into a stereotypical crazed bad guy who's lost all his marbles. Logic and commonsense are thrown out of the window in favour of a sequence of scenes which will have you banging the palm of your hand repeatedly against your forehand in frustration and disbelief and yelling "call the police, lady, for cripes sake just call the police!." The final pay-off scene is so bad I'm convinced it must have been written by a home-schooled 10 year old raised on a diet of Lifetime Channel made-for-tv movies.
You'll come to be entertained and stay to be disappointed. Or just turn it off after 65 minutes and save yourself from a headache and a sore throat.
