Overall, I am more than a little disappointed with this whole movie. I love Paul Rudd. I also really enjoy Elizabeth Banks, Zooey Deschanel and Kathryn Hahn, but in this movie, not one of them delivers what I would say was a good performance. Barely even half decent. I didn't like a single one of the characters, there was nothing that made me want to remotely care for any of them, except maybe Paul Rudd's character, just a little, but even that was barely a flicker.
Why bother watching a movie that doesn't really engage you or make you care about, or want to care about, any of the people you're spending your good time watching? You shouldn't. This is one that should just be avoided, really. Watching something else with any of those great comedic actors, guaranteed it'll be better.
