Vince Vaughn stars in this sappy remake of a French-Canadian comedy (Starbuck) about an underachieving man-child (Adam Sandler must have been busy) who finds out his old sperm bank donations have accidentally fathered 500 kids. After about 150 of the now young adults file a class-action lawsuit, our about-to-learn-a-valuable-life-lesson protagonist decides to become a loving father to all of them. This amounts to about two minutes of quality bonding with a whole string of random twentysomethings. Predictable, mildly heartwarming and not all that funny. 103 minutes PG-13.
