This has got to be one of the most boring "comedies" I've seen in a long time. The jokes, what few there were, were lame. The chemistry between the characters was nonexistent. This might have made an ok 30 minute TV show, but there is no way it should have ever been made into a full, feature-length film. As a matter of fact, the whole issue with "whose bar it is" could have been solved really simply if they'd both just ignored each other or even just stayed on opposite ends.
What there two ever saw in each other in the first place - the whole, overdone overweight, frumpy, "every-man" scores beautiful, out-of-his-league girl notwithstanding - they have nothing at all in common. That they broke up without even a single cross word between them... yeah. No. Then you bring in the girl's best-friend. She has got to be the most annoying, obnoxious, crass person alive. Again... nothing in common between her and Melissa (the main girl), either.
Of course, the required reading was there... both the main guy and the best friend's husband are portrayed as the perfect "house husbands" - within the first five minutes, Melissa literally says that exact thing about Luka, her ex-boyfriend. When Luka tells the annoying best friend that she is, in fact, mean, she cuts him off and asks if he's going to call her "opinionated," "bold," "overbearing" because of course, he's sexist. When Melissa is walking back to her car, Luka asks her if she wants him to walk with her - you know, as a gentleman to make sure that she gets there safely - she looks at him in disgust and declares "sexist!" practically spitting the word out of her mouth.
Do yourself a favor and skip this. Not even the big names (relatively speaking) could save this dumpster fire.
