There's a bit of an over-exposure problem for pop divas-come-actresses who are successful in both of their chosen fields.

When even the most popular leading ladies wrap a film, they have the decency to disappear for a little while before their next outing.

Unfortunately, Jennifer Lopez is never off our screens - both big and little - so when she wheels out the next Hollywood production what we see is J.Lo.

What we don't see is sparky waitress Slim, who marries successful businessman Mitch (Campbell) and, before you can say chauvinist control freak, she's in the club.

Such is Lopez's stellar omnipresence that you never get it out of your head that it is the millionairess with the impressive bottom up there - not a woman whose life is about to take a turn for the worse.

Mitch - after Slim discovers he's having an affair - shunts the feminist crusade back where it belongs with the statement: "I earn the money - I make the rules."

So she does a runner, but Mitch, with his dodgy connections in the police, is always just one step behind - or at least his meat-headed goons are.

"If I can't have you then no-one will," he rasps, spurring her into a quick course in martial arts and a countdown to the domestic battle to end them all.

It's pretty feeble stuff, never quite making its mind up whether to be a visceral thriller, an action yarn or a romantic comedy with a bit of violence thrown in.

Lopez does 'tender' the way Margaret Thatcher used to, while there's no degrees of grey to Campbell's performance - he's just a nasty piece of work.

A ludicrously under-explored sub-plot featuring Slim's absentee dad just gets in the way, leaving Aimee Mann's haunting title track the only reason to get excited.

After approaching two hours most people would declare enough is enough... and leave.
