This indie film walks the well-beaten path of a couple with commitment issues and features a silly plot device that allows one of them to obsess over an absolute stranger. The "twist" couldn't have been better spotted miles off if it were surrounded by road-flares.
And I'm getting a little sick of poorly written dialog in screenplays hiding behind what used to be called "cinema vérité". If you're not shooting a documentary, write dialog that either progresses the plot along or drop the stuttering, meandering "realistic" speech patterns altogether. It's boring watching actors stumble their way through scenes in which they need to communicate verbally.
On a side note, it's such a shame that Rashida Jones can't land better roles. I think there's some untapped potential there. Or maybe it's just because I think she's cute. Who knows?
