Critics are less than enthused about new prospects at the weekend box office, leaving comedy Confessions of a Shopaholic, crime thriller The International and horror Friday the 13th with more to battle than each other — while E1 Films bows the Oscar-nom’ed documentary Trouble the Water.

Shopaholic, based on the Sophie Kinsella novel, opens wide through Touchstone Pictures and stars Isla Fisher (Wedding Crashers) as a college graduate with a shopping addiction. Touchstone is looking to lure female viewers in the same vein as 2008 box office hit Sex and the City: The Movie — which generated $18 million in Canada for Alliance Films despite soft reviews.

It remains to be seen whether female moviegoers will be able to sway their boyfriends to see the film on Valentine’s Day.

The Canadian Press says Shopaholic is a ‘waste of Fisher’s infinite likability,’ while Reuters notes the comedy ‘quickly maxes out its welcome.’

Looking to court slightly older couples, Columbia Pictures bows The International, which stars Clive Owen and Naomi Watts as an Interpol agent and district attorney looking to bring a powerful bank to justice. Jason Anderson at Eye Weekly writes the thriller is a ‘perplexing and pretentious variation on the Bourne [franchise],’ while NOW Magazine‘s Barrett Hooper calls International ‘smart but dull.’

Also getting thumbs down is Warner Bros.’ horror remake Friday the 13th. Toronto’s Eye Weekly‘s writes ‘it certainly doesn’t amount to much, but it’s not appalling.’

Meanwhile, E1 bows the Oscar-nominated doc Trouble the Water in Toronto Friday, looking to court audiences before Academy Award winners are unveiled next week. The acclaimed doc tells the story of an aspiring rap artist and her streetwise husband who get trapped in New Orleans during Hurricane Katrina. It is directed and produced by Tia Lessin and Carl Deal, who were producers on Michael Moore’s Fahrenheit 9/11 and Bowling for Columbine.
