I admire 'Kissing on the Mouth' for its frankness  pubic hair cutting and masturbation, especially from the lead/director Joe Swanberg. They weren't afraid to show trueness to everyday "private" occurrences. Unfortunately, the film falls under the 'The Brown Bunny' realm, though with a slightly more developed plot of jealousy. Yes, it mirrors 'Bunny' with a whole lot of nothing going on, or too many cinematography shots focused (or sincerely unfocused) on absolutely nothing  feet, hands or genitals. Again, unfortunately, I can see why this film was released, and why people are renting: true life sex scenes and full frontal (equally, both male and female) nudity. Other than that, it was a complete waste of time. We quickly learn of a post-college male/female roommate pair in which the male has obvious feelings for the female that sees him as just a friend while continuously having sex with her ex-boyfriend. Other than that, we are subjected to the every-day events of their boring lives: she works for her parents; he works on an extremely uninteresting sexual awareness project on his computer. For this all to work, the dialogue has to be interesting and the acting real. Neither work and it's as boring as watching someone drive for an hour, i.e. 'The Brown Bunny.' The only actor that stands out is Kate Winterich, and even she does some questionable acting. (The DVD extra with her in front of a mike is actually worth watching/listening to.) Again, I admire the filmmakers, especially Swanberg, for baring it all and not being afraid to expose themselves or shower-habits, but overall the film falls flat. It has narrations that doesn't fit the scenes, too many boring everyday events and unconvincing acting that you wonder, other than the soft-porn factor, why you rented this.
