NEW JERSEY - On a Monday evening in Cranford, dozens of families gather around a 40-foot-TV to teach their children a lesson about screens. Woody and Buzz have survived sadistic neighbors, evil toys and tyrannical daycare rulers. But in "Toy Story 5," which hit theaters June 19, their latest enemy is something millions of parents already know well: a screen. Around the country, parents are using the movie to open up conversations in their households as they look to find a balance with technology.
