Knocked Up (2007) on Netflix

Ben Stone, like his four roommates, is a schlub and slacker. Their sole work - unpaid self-employment - is creating a website that identifies where scenes of women's nudity appears in mainstream movies. Alison Scott lives in a suite in the house of Debbie and Pete, her sister and brother-in-law. Slightly insecure Alison masks that insecurity by trying to control her life, much like her sister. Alison celebrates her promotion as on-air reporter for E! by going out with Debbie to a club, where she meets Ben. A generous gesture on Ben's part leads to Ben and Alison hooking up, which by the sober light of day she realizes was probably a mistake as they are totally incompatible. Conversely, Ben really likes Alison, who generally would be considered out of his league. However, that liaison results in Alison becoming pregnant. After thinking about the implications, she decides to keep the baby. Beyond the personal issues, Alison struggles with how this pregnancy will affect her new job, especially in the eyes of her image conscious bosses, Jack and Jill. Despite being a big kid himself, Ben, wanting to do right by Alison, supports her in any way he can. As they are both "nice" people who strive for the traditional when it comes to family, they decide to give their relationship a shot despite their incompatibility. Especially for Alison, her primary concern is not ending up the way of Debbie and Pete, who too are incompatible, who only married because Debbie got pregnant, and who both seem unhappy in their married life.
