The writer-director Valerie Breiman, in her first feature, has put together an inconsequential but charming romantic comedy starring the long-stemmed, unpretentious beauty Famke Janssen as a Los Angeles magazine writer and Jon Favreau ("Swingers") as her boyfriend, a wise-cracking, rather infantile painter. The movie offers little more than the latest forms of sexual banter, but the teASINg mock crises are easy enough to take, and the two stars have a nice rhythm together. Janssen, with better material, could blossom into the next Julia Roberts; she's pretty irresistible even in this low-key stuff
