I read the comments and expected to hate the movie but I was pleasantly surprised after watching it. Described in one word, I'd say the movie is "endearing'. It's clever in a quaint way. It's a movie you might watch on Father's Day as it's main themes are a child's instinct to know their father and a father's instinct to care for his children, even if the father is only a sperm donor. It's a feel-good movie with a unique message, one of Vaughn's best so far I think.
Deadbeat dads will hate it.
