Us Rating: **

Natalie Portman and Ashton Kutcher share strong chemistry in this flick, but the story feels weak. The two attempt a friends-with benefits arrangement, but after a while (surprise!) it doesn't work: She gets jealous when he sees other women, and he's been falling for her the whole time. Despite the film's somewhat edgy premise, it's ultimately a conventional romantic comedy -- and a rather dull one at that.
