They just don’t make teen-age pregnancy dramas like they used to. Case in point: the Lifetime network acknowledges Father’s Day with the bland message melodrama “Too Young to Be a Dad,” (8 p.m.).

As a kid, I remember taking sidelong glances at reruns of the 1959 potboiler “Blue Denim,” starring Brandon de Wilde and Carol Lynley as high schoolers in the family way. Its scandalous story earned the movie a “condemned” rating from the Catholic Legion of Decency. The fact that I was putting my immortal soul in peril just for watching “Blue Denim,” made the forbidden film all the more irresistible.

The only sins associated with “Too Young” have been committed by the screenwriters, who saddle teen parents Matt and Francesca (Paul Franklin Dano and Katie Stuart) with unbelievable dialogue. A promising young honor student, Matt offers to tutor Francesca in geometry. But the bored and troubled girl would rather offer Matt an anatomy lesson. She’s had sex before, she tells him, “to relieve the stress” put on her by her ambitious parents. In the logic of all such dramas, the couple fumble through “it” once and within moments, Francesca is suffering from morning sickness.

Dano and Stuart do a credible job of capturing the awkward experimentation that passes for youthful passions. Unfortunately, once Francesca becomes pregnant, “Too Young” switches focus to their parents. Matt’s mom, Susan (Kathy Baker), faces public humiliation while Francesca’s cold doctor father quickly arranges for the baby to be adopted by a deserving professional couple. Matt’s own dad (Bruce Davison) retreats into his busy work schedule and marches around the house in an emotional brain-lock. I don’t want to give too much away here, but the movie resolves itself with a sappy, happy ending that makes the average After School Special seem like a gritty documentary.

“Too Young” was produced by Lifetime in partnership with the National Campaign to Prevent Teenage Pregnancy. Like propaganda movies of old, it makes underage sex and pregnancy seem both dangerous and dreadful but not as excruciating as watching “Too Young to be a Dad.”

The documentary “American Standoff,” (7 p.m., HBO) is the first documentary I have reviewed that offers a sympathetic look at a strike or a labor union.

“Standoff” chronicles the efforts of the Teamsters Union to organize at the terminals owned by the Overnight Truck Co. Produced by Barbara Kopple (“The Hamptons”), the film presents first-person interviews with strikers, organizers and Teamster leaders, as well as a spokesman for Overnight. It also chronicles the bitter division within the union and the efforts of James P. Hoffa Jr. to re-energize the Teamsters while avoiding his father’s mistakes. Like many Kopple productions, “Standoff” is both fascinating and indulgent, a 90-minute film that seems about a half-hour too long.
