This movie has its share of laughs, but it's also Ron Howard's most personal film, and clearly his most ambitious—a multifaceted essay in fictional form about the diverse snares of child rearing. The movie tries for so many things in so many different registers—there are a number of fantasy interludes and raunchy gags along with an overflowing cast of characters (including Steve Martin, Tom Hulce, Rick Moranis, Martha Plimpton, Keanu Reeves, Jason Robards, Mary Steenburgen, and Dianne Wiest)—that the results are often unwieldy, but they're certainly heartfelt: Howard's grown-up sentimentality is the perfect antidote to the infantilism of Spielberg and Lucas and their disciples. The film never shies away from real problems, and the complex mix of comedy and seriousness in its treatment of the pitfalls of parenthood steadily grows in feeling and power. The movie may wind up being as messy as it argues that family life is, but it commands admiration and respect. The screenplay is by Lowell Ganz and Babaloo Mandel, based on a story that they wrote with Howard (1989).
